Like me, you probably heard that you cant use LEDs/ HIDs in reflector style headlights as it will blind and dazzle people. in this short video I prove that you can.

POWEEER!!! 😂😂😂
Dayyyuumm, you're right! Lmao it really is a young JC 😂
Same voice, same hair, and same neck 😭😭
POWAAAAAAH!!!🤣🤣🤣
If you're getting a weird spread with an led bulb, put the halogen bulb back in the original socket that came with it and try to find out the right distance a light source needs to shine upon the reflector inside the housing itself. If the led bulb is retracted back from that point, due to any reason, you'll get a blinding light spread from the reflector. But if you further push the led bulb inside the housing just so that it shines at the right spot inside the reflector, it casts a perfectly sharp beam without any blinding streaks of light.
This is what I learned while modifying the headlight on a stock Honda 100cc Economy class bike.
Thank sir, this is the answer I was looking for.
And make sure the length is correct of the LED bulb cos if it’s too short, the beam pattern will send everywhere and you’ll end up blinding people.
Aaah I see
@@chacholiades you should try Philips or Novsight in reflectors! They should produce exactly the same beam pattern and hotspot in the middle. I run Novsight LEDs in my car in reflectors. It’s not mega perfect but it leaves the cut off line and not dazzling oncoming cars. You should try these bulbs!
How did you modify the headlight to change the distance between the reflector bowl and the led. Did you shorten the led or push away or put closer the reflector bowl from the led bulb itself?
yeah i love putting led bulbs in any reflector housing .. it just responds better
We have so many deer where I am at. I use led headlight bulbs in my Toyota Echo instead of welding up a deer bumper. Sure helps.
Really it just depends on the LED bulb configuration, and depends on the housing. I swapped LED's into my old Ford truck and the low beams are much brighter and make the road more visible than the halogens. No question. However, the high beams are essentially unusable because they scatter and disperse the beam so badly. So in that case it's a tradeoff at best. I plan to stick with the LED's for now just cause I've got little need for high beams on the reg. Cheers
Great video dude,nice to see the comparison between them with the headlamp,the led one is certainly a lot better.
Certainly a lot brighter. That was the point of the video to make a comparison between them.
it all depends on the led bulb and there's hundreds of different ones, you need one that can adjust on two axis forward and backwards and rotational its the only way to get the focus correct. the halogen bulb let no light go foward the light is aimed back towards the reflector and theres a hood over the highbeam filament to stop light from going too high and blinding drivers, leds are getting a much better design now but they're not quite there yet
A fantastically entertaining and informative video ! 👍
I'm glad.
Cut off line in halogen bulb is more prominent
Bluudy!! I’ve said exactly what you said “so I think you can get away with these in reflector light” I enjoyed watching this video and You explained it really well and so informative! I have Novsight H7 LEDs for my Golf mk4 in reflector housings and they come out very nicely! Their nice and their white! I rarely get flashed by one or two cars as I had LEDs for a year almost and I didn’t have any problems and the beam pattern isn’t perfect as they are slightly blurry but if they are installed correctly and without dazzling oncoming cars. What I’m slightly worried about is when I take my car for an MOT and I got a feeling they will fail on LED headlights on “Headlamp light source and lamp not compatible” it is aiming and set correctly and it’s not aiming too high or too low. If it does fail on headlights then I swap them out and I can put the LEDs back in afterwards. I wouldn’t fancy put HIDs in the reflector housing as they are ridiculously bright and blind other road users, they’re better in projector housings if used correctly.
You should try Philips Ultinon Pro9100 LED or Osram nightbreaker LED as they make really good bulbs and doesn’t scatter the light everywhere at all like cheap shit LED bulbs so. They sound produce exact same beam pattern just like the halogen bulb!
LEDs dont blind if you buy the right leds. Always buy leds that have only 1 row of leds because they mimic the same position how filament halogens work and also align it in the right place so it actually reflects in the right direction
You can adjust the good ones, the turn from 12-6oclock and 9-3
LED bulbs you buy these days are ideal improvements over halogen headlights. It’s as simple as having a bulb with only 2 sides of LED chips, and ensuing the lit sides of the bulb are at 9+3. Yes it’s 400% brighter if you’re within the identical beam pattern to a halogen bulb. But a halogen bulb is also blinding if you look within the beam!
The older the car the better the LED experience, Canbus just complicated the cheap bulb upgrade life!
Types of HIDs exist aswell. There's the HIDs for projector housing and HIDs for reflector housing, which is another reason people think they seem ridiculously bright on certain cars.
L.E.D head light bulbs, as the technology stands right now, are actually best suited for reflector housings. H.I.D is still best for projector housings. But no matter which bulbs you use, blinding people is ALWAYS a problem with improper alignment, not bulb type.
That's false, L.E.D. are best suited in projector housing when it comes to down road visibility. I'm saying this because I have LED in reflector and in a projector, the projector by far has better visibility and the reflector has about the same visibility as halogen
The thing is reflector inhirently produces more glare than a projector. There's a limit to how much light you can output out of a reflector. As the glare goes up at the same rate.
Problem with the H.I.D bulbs, they are ridiculously bright and end up blinding/dazzling oncoming traffic especially with Range Rover with HIDs as standard when it left the factory, they are so bright and couldn’t see a thing at all at night
@@davidriley9194 again, that is an alignment issue. Larger vehicles, like a land rover/range rover, have to have their lights aimed a bit lower that a passenger vehicle because they sit higher. Glaring light is the result of headlights not being aimed ever so slightly to the right(from the perspective of sitting in the car) so they do not blind oncoming drivers.
@@MrCougar214 I honestly think when drivers brought the Range Rover/Land Rover, like you said, they need to lower the headlights down cos I don’t think they were set right when it left the factory, aiming far too high cause dazzling oncoming cars and that when I had to flash my headlights to turn their lights down
I have leds in reflectors and aiming them is everything. I don’t have anyone flash their high beams at me. I also went with a Phillips ultinon bulb that is one of the few legal bulbs in other states. It took me 2 days to aim them. First day I had a few people flash their high beams at me and I lowered them 1.5” @ 25 feet and now no one cares.
The led put out a wider light spread than the halogen
Putting in my Mirage
I've been blinded since 2010 when every single landrover/range rover started blinding me with their slow angle adaption and already raised headlight position...
Great vid, thx👍🏼
your the next clarkson
I can dream
i have a golf 4, can you make a video to install led bulbs ??
im very interesting.
sebastian
Do you have a spare hid bulb you could compare to the led? That would be great to see.
Afraid not. But if I get a set I will do!
Do you have a link to them?
I've got leds in my citroen c2 daily and have never had a problem and I left them in for the mot.
@Gareth Evans yea think I've turned mine to 1 dude.
Haha you made a video on pretty much what I said. Ive got HIDs in reflectors in my mk4 astra and like u said I keep the beam lower than usual
:)
Question would u recommend hids over leds for reflector headlight
@@rafz9147 well hid have more light output.. I.e 360 degree like a normal bulb.. leds only tend to have 2 led chips giving a light output at 180 degrees..
@@zhoaibraja2992 would i have to change reflector bowl aswell to fit hid
@@rafz9147 no idea.. I didn't personally.. I just slightly lowered my lights aims when I fitted em.. however you can get actual HID kits that work with reflector headlights.. They have the letter "R" in the bulb code e.g. H7R instead of just H7.. u can look into them too.. They basically have a sheild built onto the bulbs themselves so they work properly with reflector headlights..
“Let’s bost eht” Lol i love the french
Just purchased led H7 bulbs for my 2019 Golf but a bit confused has led bubs are low energy and are cold to the touch ie my Christmas tree bulbs are all led and you can touch them where as the old halogen type tree bulbs would burn you so how come car led headlight bulbs need a fan?
To dissipate the heat of the led chip if the led chip gets to hot it will eventually burn out now some leds have just a heat sink no fan option my stock leds has heat sink and fan I hope this helps
I’ve got H4 LED bulbs in my Bora’s reflector housing and they’re so much better and safer to drive with at night! Not to mention that there is a clear line cut of point!
Mines not mega clear define line. But is good.
Hey Josh, which LED bulbs did you go for and did you have any issues with the length of them? Any modifications needed at all? I'm changing the lenses on my Bora headlights as they're clouded up to shit, and want to get some new bulbs too.
Danny Jones hi mate, I used Night Eye H4s bought off amazon - straight fit, plug and play and they fit inside the headlight with the cover able to close without any modifications. Passed an MOT no worries too when angled correctly! I would definitely advise installing LED w501 sidelight bulbs if you’re installing LED dipped/main beam bulbs otherwise you’ll still be stuck with the horrible yellow halogen glow inside the clean, crisp white LED light. I used to get condensation in my headlights with my halogen bulbs because they create a lot of heat whereas these don’t get too hot at all so there’s no temp change inside, thus no condensation!
@@joshscott9055 thanks for the reply, Josh. Just had a look at those on Amazon. I've been looking at the Novsight ones which seem to have good reviews...working out if passive ones would be better than ones with built in fans. Also need to make sure that the level adjustment still works on my Bora...252k miles & 15 years old! I have led 501's already. Just so sick of the crappy output from the halogens. Truly the worse I've ever seen in any car!
Danny Jones I remember my halogen bulbs were shocking. I’ve got a pd130 highline with 98k on it on an 05 plate. I believe my ones have the fan built into them - they were just so easy to install! Of course I took the bumper off but what I mean is that there were no ballasts or modifications required etc
No high beam demo?I have tried led on my F150 ,the highbeams always suck so to me a waste, trying to use in a reflector style housing
If set up correctly there should be no reason why we can't run led bulbs in reflector headlights, we just need to convince the MOT tester 🤔
My Siggy has H.I.Ds in a projector lense and this year it passed no problem however they did say the MOT regs would change in May and any vehicle with HIDs would need headlight washers and a self levelling system to pass now they did not mention LEDs but i would not be surprised if the same applies so next year i will need to put back in the standard halogens for it MOT as mine is the SRi and not the Elite that has the adaptive lighting fitted as standard with all those systems.
I would have thought leds and hids fall in the same catagory
Can confirm. I failed MOT in May because of HIDs. They were installed in projector headlights but they didn't have washer jets. Stupid law to be honest, probably invented by some old tosser who hasn't a clue.
@@MS-gb3ev Haha. Yeah I knew they changed the law in april/may
I just got a 2019 f350 sport and because of it being a sport package I couldn't get the led headlights because they couldn't be added because they didn't have them in a black shroud only chrome and I got all LED bulbs but haven't pulled the trigger on installing them and now that I see they stay some what sharp line (depending on all the difference housings) I believe I'll take this weekend to install and treat out in side my barn to see how they do after adjusting which seems key👍🏻 before just getting a good aftermarket retrofit 😇 cheers from across the "pond" 🤠
I'm glad it helped dude. Hope they look good!
it depends also on type of the reflector how to install the LED bulb. if the light refraction is horizontal or vertical ... in the same way you should install the (two-sided) LED bulb.
Please explain

m8 you look and sound just like jermy clarkson its very eerie
I use ledbulbs in my golf 7 reflector headlights for 3 years, never had problems of people flashing there lights because mine are to bright...
Great video, but for the love of God, don't buy led with 360 bulbs, they are awful. Bulb shown in this video is the best kind for good pattern.
Sir , what about halogens white light
Can I ask you a question?
@@kyactus4325shut up
wel the glare of the led is the problem not the hotspot...
HAMMOOOOOND!!!!
Do you have a link for the bulbs, I want to fit them on my mk4
If you look back a few videos I did a review on them on the golf. The links in that video.
@@bluudysgarage OK thanks.
Nice vid. I think manufactures have tried your idea… probably not better so they stick with the 2 sided output.
Think I might treat my Beetle.
The problem is people don't do their homework and by the correct bulbs for their car. They just grab the brightest bulb they can find throw them in and that's when you have scatter and you blind people and not enough downlight.
what about hid on reflectors?
With the 360 degree led you will get scattered light i.e less LUX and blind everyone else
YOU DONT DO THAT it should be either side
Halogen are 360 do they blind everyone?
What LED do you recommend for reflectors man? i have a smart fortwo 453
Love the video, smashing content.
I'm glad. I was trying something different.
I've often heard people complain about being dazzled when the subject is raised. The fitting of LED in old halogen lights is illegal so it's not really a matter of opinion.
You didn't mention a decoder for more up to date led lights for headlamps. Not all work and will flicker or flash without coding.
I think your referring to canbus related lights. Yes your right. Some will flicker but prodomently you find that issue in smaller lights like side lights due to the smallness of the lights they don't always have resistors in them.
As a hgv night driver you can alway tell the age of the car dazzling you with these led bulbs there is a reason they are not for road use in the uk
Fair point. Never said they were legal. But like most mods done to cars there lots that aren't legal.
Bluudys Garage yep no worries I not dissing your channel and am up for modifying your ride this is why I’m one of your subscribers. But when it affected others it a mod to much just my thoughts
@@s9enny I appreciate that. It's cool man.
Have you taken the golf out in the dark with the led bulbs fitted
I have. It's so much better
@@bluudysgarage Aye, unless your the poor twat on the receiving end of that lot! Your experiment is very unscientific, but even you could see the beam cut off was clear on the halogen lamp, and non-existent on the LED. Bear in mind too, you noted an inch or so higher beam top edge on your garage wall, a couple of feet away from the lamp, now translate that to half a mile down the road and your beam is now 20 feet higher to the top edge. I've come face to face with LED retrofits, and they're nothing but a menace on the road, and a danger to other road users, but then what would we expect from a VW Golf driver?
Mythbusters? Nothing like, style or otherwise!
@@28YorkshireRose12 Was thinking exactly the same!
Thanks for that mate, I was going to put leds in my front fog lamps, I haven't yet but think I will now.
No worries man. Glad you found the video helpful.
It still classifies a headlight conversion therefore it's still illegal. You get caught you're MOT will be revoked on the spot.
@@ShabaaUkelele You can't have your MOT revoked, do you even have a car? The police issue a rectification notice and you have a period of time to fix the issue. Your MOT isn't "revoked" or take away from you
@@seancorrigan3531 although a PG9 offence is for commercial vehicles that is a revocation of MOT. I'm a class 1 driver mate not just having a car. I'm sure they can revoke MOT on non commercial vehicles but I might be wrong
Update. It does not matter what you call it. Revocation or prohibition the end result is the same. You need to fix it and need to retest it in both cases plus you can't drive the vehicle on either cases...
www.west-midlands.police.uk/your-options/vehicle-prohibition
Just one example
@@ShabaaUkelele noise down you... Look at the MOT cert it says it is only valid on the day of test... So how can you revoke something that expires after 24 hours??? You are clueless...
While I drive mine I have a lot of trouble with stray light. Two examples: driving at night and I multiple highway signs over a course of hundreds of meters are lit up very good. Second example: standing behind cars and the lights reach their cabin. It’s weak, but it’s there while it shouldn’t
I installed a new headlights today because the previous one wasnot original and the whole housing was kept together with just a single tierep.
Does any of you know what the solution is? Realignment of my headlights or not
What type of bulb what you using?
Bluudys Garage H7 LED’s with those lumineon LED chips
It will be more than likely the bulb. You try a normal halogen style and the pattern will be better.
@@bluudysgarage I send you an email with the pictures of the light I see both from within the car and out the car. Check your gmail :)
@@danielklm brilliant thank you.
Would these pass a MOT?
As long the beam pattern is correct and the alignment is ok
😎👍
Folk said the same of HID bulbs in reflector housings, i fitted 8000k HID bulbs in my Golf Mk4 and they've passed the last 2 MOT's, They don't blind anyone.. just give a better spread of light on the road..., This is not to say every reflector housed headlight will be fine though.. it's a trial and error thing.
Did I spy a supra in the driveway?
Comparing with no projector?!!
LED bulbs are just a crapshoot, there's so much variation - some may well work but many more don't, it's not chance since some are clearly better designed than others but the huge variety on offer leads to many being unsuitable for the housing they're in.
if a much stronger source of light doesn't cause dazzling, why do you think there's a legal limitation of 55W for a headlight bulb. just because your beam seams even, doesn't mean you won't dazzle other drivers. the problem is, when you're passing with another car in the night time, you're forced to look in it and more powerful source of light will dazzle you anyway. this is why modern cars with factory fitted LED reflector headlamps NEVER have their LEDs visible from the outside. if you look into the headlight from the front of the car, you won't see it, it's placed behind the reflector itself. and that's because it's such a strong source of light it can't be placed the same way as halogens are. I do travel a lot in the night time, and it's absolutaley outrageous how some people have no respect for other drivers whatsoever, fitting some dodgy bulbs and not only they're dazzling, but often I can see how little is lit in front of them. please, just stop. if you've got an older car and your lights are no good, don't treat putting stronger bulbs as any kind of solution. get new lights or get your old ones cleaned/reconditioned. it's as if you had your window wide open in the winter and instead of closing it down you'd be turning up your heater.
Use a cardboard on the wall, thus you can mark the pattern.
i dont think u can. because reflectors are not like preojectors. they shine more light and can dazle others at night. police can stop you since it shining lots. if it was projector. the shine would be normal level
no ones flashed me with my LEDs so...
You remind me of Jeremy Clarkson :D
pause on 4:24 and compare beam geometry. There is no geometry with LED bulb, its just blob of light, no V shape to it. V shape is important. Also try to pass MOT with those LED lights, would be interesting to know the result.
Lights are optical devices, not just some dumb flashlight, where brighter is better.
To see lines, V shape and cut off, shine the lights to white wall from about 10 meters/yards (30 feet) and compare that pattern to LED light. I bet it will go over the line and that means you are blinding other drivers!
I’d be interested to see if it passes the headlight beam aim test at the MOT station, that would be the true decider
If beam pattern and colour will match correct shape they will pass MOT. But you have to tell about this modification your insurance company, just in case of accident they may refuse your policy.
Problem is it is technically an MOT fail as it changes the "type approval" of the car. The beam pattern won't be right in all headlights though.
There are no regulation LED headlights which you can change the bulb in (they are all sealed and mega expensive) and no regulation was written for them.
NOW ... I'm REALLY confused ....
Its not a question of led in reflector housing, of course you can fit them if they fit. As you saw yourself the led had no beam pattern, light was all over.
The line between top/dark/other set of eyes and bottom/light should be as sharp as possible. That way no stray light ends up in the other guys eyes. If you used a headlight adjusting device youd see the beam pattern is off allot, just like xenon in reflectors. When reflectors were made were designed around incandescent bulbs. Also reflector have a limited light output permitted, just because they are not good at projecting precisely.
On a side note i have been blinded by more than once by oncoming cars with oem led headlights, man they are bright, and right in your eyes. Those were top line cars, manufacturers care more for the customer they sell their car to.
My own car has reflector headlight, and i was thinking to get some led h4 for it, wiring is weak/old bulb gets 2v less than battery, but ill live some more with my little candles.
Golf mk4 ❤️🤙🤙🤙🤙
you should be standing at least 25 feet away from headlight to see if this makes you blind or not.. i am sure you are about to consult eye specialist after this..
mk4 head lights are poor. they need stronger bulbs or fit r32 ones
R32 use have the same reflector housing. I have a pair.
they use xenon bulb n ballast
@@69bock69 Not all R32 come with Xenon's. The Golf 4 headlights are actually quite good. What I like about them is the circle pattern you see when you are driving in the tunnel.
with standard bulbs there poor. and I'm not 100% but 99% all r32s come with these headlights .
Daniël Begovic mk4 lights are absolute trash
Very scientific. Lol
Now won't Blind anyone unless you aim then high
Can I ask where you got your led bulbs from please 😃
Amazon :)
Bluudys Garage thank you👍🏻
@@MrSlapntickle75 get them from wish!! Free and only pay postage and take 3 years to come
Do you have a link from where you bought these led lights from
the biggest problem is people not adjusting their light to point to the ground and not straight out into infinity - either they don't know how, don't even know that they can, or are just dickheads who have no regard for other drivers
👏👏👏👏👏👍👍👍
Who’s a one car lol sorry mate couldn’t resist
I'm lost.. what have I said now.. lol
When you said not specific to one car sounded you was say wanker really posh I’m mad don’t worry great video
@@davejones538 Haha thanks man
i love how everyone bangs on about you cant use these or xenon kits for example, as they,ll blind everyone. Bollocks! iv been sat infront of loads of new vehicles on the road or motorway at night,and how bright and dazzling these new headlights are is not even funny, its dangerous. And thats totally acceptable and fair....yeah ok.
HID take the piss. Great for the driver, bad for the thousands of other people who are stevie wondered by them
SHIFTY he’s talking about the newer cars with LED headlights from the factory. Even though they are made for the correct housing, they still blind people at night
What about the Cops. I wish that LEDs were road legal by law. They are clearly better for driving, and if set correctly no different than stock bulbs.
bax442 their not illegal. I have spoken to a police officer about installing LED in my reflectors and he said I can do it
When I drive down road with my factory fitted led bulbs don’t it just blow up in ghost busters they said not to cross the beams lol
Hahahaha
It depends on the power of led bulbs. Just dont use any bulb tht goes over 20-25w of power consumption and the led source is matched with the halogen filment on 1:1 ratio
Im sorry, i cant stop comparing the way you talk to monty python and the holy grail. You should run around with the headlamp housing behind someone, you know, instead of coconuts!
Hello
Bye.
Your headlights will fill up with dirt, because you can't put the caps back with the LEDs. And it's clearly visible that they shine diffusely on the wall and in your (camera's) eyes, while the halogen is focused. That's because on this chinese led the diodes aren't in the same position as the filament in the halogen so they go out of focus. This is the Main reason they blind, second being outrageous brightness of some diodes. If you want diodes so badly you should consider ones from reputable manufacturers like Osram and Philips.
Testing headlights in day time, clap clap
halo is better...
If your LED light was 360 as you suggested, it wouldn't work as it would scatter the light in the housing and cause a blinding glare. This has actually been explained extensively by a professional. If you check Headlight Revolution on TH-cam, they explain all the reasons why poorly designed LED lights are bad for the road. What you need is a halogen bulb with 6500 lumens. That is, your light temperature is more whiter then the 4000 lumens halogen you are used to and I noticed that the beam pattern of the OEM halogen differs with the aftermarket LED light you fitted which means that there is no anti glare on your led, so it will cause glare at night. So you couldn't bust the myth because it is not a myth
What LEDs do you recommend for reflectors man? i heva a smart fortwo 453
Those housings were not made for LED bulbs, you need projectors to properly run LED bulbs. You can clearly see the light dissipate in that housing when you put the LED bulbs in them. You're trying to justify your pre-conceptions that you're able to run them, which is not true.
For reflectors halogens are best then ?
You’ll going to blind the oncoming traffic! Stupid idea!
