Cheap Ebike light kit - How to wire up

- เผยแพร่เมื่อ 21 ส.ค. 2024
- Whats up youtube i bought this cheap light kit on aliexpress (link below) and found out the brake lights wont work with my controller and there was no wiring diagram that came with the kit, so i figured out how to tap the brakes in without using a controller. This kit seems pretty popular due to how cheap it is and it comes up first in my google search along with similar ones with the same wiring. Hope this how to makes sense any questions hit the comments.
get the kit here - www.aliexpress...

*update after running the lights with 72v i noticed the blinker LED's start to smoke and burn up, but brake, running, and headlights are fine. Just to be safe id stay at 48v with this kit*
Thanks, for the info. If the main power plug is connected to a controller for a 72v bike, would it be receiving 72v or would the controller be outputting a lesser amount of voltage?
@@maaz322 hey no prob so the main power is technically comming from the battery i just have it screwed into where the battery screws into the controller instead of splicing it into the battery wires if that makes sense. But yes its getting the full 72v i double checked the voltages to all the LEDs. I have some blinker lighta coming that supposedly run off 48-72v so ill update then. But the light kit is still running strong i just dont run the blinkers for more than a couple seconds
Great video, cheers for the help! To make it simple for anyone watching and still confused, all you need to do to make the brake lights work is swap the red and black wires on the female JST connector for the brakes on the harness which plugs into your e-bike controller (you could alternatively swap the red and black wires on the male JST connector coming out of the e-bike controller, but it’s the same difference). Do this for both connectors (left and right brake), hook it all up and it should work. These cheap Chinese kits often get the ground and power wiring mixed up/plain wrong which is why this problem arises.
Appreciate that! Good call on the brake wires, since my controller didnt come with brake wires or any sort i had no way of figuring that out!
@@EmxBrandon of course! Your video went a long way in helping me figure this puzzle out 😂
@zaxzaxerly9207 😂 for real! Gotta love that chinese stuff with absolutely no instructions lol
haha can't beat it for ten bucks tho🤣@@EmxBrandon
@@zaxzaxerly9207my head is still doing flips trying to understand how the wires are getting tied in.
I understand the wire is wrong, now what? XD
Thanks for the help I scratched my head for a bit and with your help , no scratching. once again thank you
No problem!
Thanks for this bro, i couldn't get my brake lights to work. They just stayed on, but using your trick in this video it works perfectly with one brake. I have my other brake connected to the controller to kill the motor for any reason.
Thats awesome im glad i could help 🤙
I found the issue why the brake light always stays on if you're interested
@@DyLemmaOG I am having the same issue. I'll appreciate any input from your experience
Thanks a lot for your tips! Just perfect! I was kinda lost how to connect these wires but now no doubts! Thanks a bunch!
Hey! No problem glad i could help!
THANK YOU MAN! FINALLY BRAKE LITGHT WORKING!!!
😁🤘 glad i could help
This kit is actually voltage rated between 6-60V by Bafang.
Right on, that makes sense its heen handling 72v no problem other than the blinker relay thats built into the taillight board.
👍👍👍👍👍👍
🤘🏻🙏
So if I run this kit through a step down converter for my custom 12v lights do I need a separate Stepdown converter for the brake line? I don't want to burn out my new lights... Cheers!
Very good and clear video mate.. nice one thanks👍🏻🏄♀️
Thanks man i appreciate that 🙏
So basically if you want a plug and play systems dont buy this. Youve plugged it straight into the battery but as the battery is plugged into the controller, how do you do this?
Depends on the controller, I just used ring terminals and attached them along side my battery terminals bolted to the controller. If you ha e a generic controller you can install the main plug for the light kit on the indicator plug.
I got this all wired up on my scooter, but couldn’t get the brake light to flash, got the headlight to flash when I pulled the brake, but not the taillight
Dang almost sounds like you got a bad harness that wired wrong. The brake wires should be pretty unmistakable.
@@EmxBrandon I can get the brake light to light up, I just have nowhere to plug the brake sensor plugs in. My controller doesn’t have anyplace to put that, just a “light module” with power out for the headlight and tiaillight. When I plug into the headlight cable, everything works but the flashing tail light, when I plug into the tail light cable, only the headlight flashes
@terpypanda7105 hmm im not sure about the head light flashing, but thats why i cut the brake light connectors off and by passed them in the video since my controller didnt have a spot to plug in brake wires either.
@terpypanda7105 i believe i cut the 2 red brake wires and wires them directly to one side of the brake lever and wired the other side of the brake wire to a ground and it worked out.
"that's all tidied up" yep that's me all over😂 How's the front light as a night light, one that allows you to be seen or one that allows you see? I am thinking of a cheap project light the wuxing QD236 headlight, as I have a red connector on my controller doing nothing.
🤣 and its not terrible the lights pretty small but its bright enough to see a decent distance ahead and plenty bright for others to see you. I looked up the light your talking about if i got the right one it looks about the same size which is nice and easy install
Ive been procrastinating but i will have a night ride vid soon even if i just make a quick short 👌
@@EmxBrandon That would be cool, hit me up here if/when it drops, YT a bit sketch when it comes to notifications but subed anyway - Making vids does pose a challenge, I've been trying to make some shorts but still finding time is hard, I have loads of footage but my lappy is aging and does not handle shotcut very well but my PC is old tech but high-end but is used with a terrible keyboard and as a media station. I have a torque-arm vid in post atm.👍
I feel ya on that ill let you know 🤙
And no doubt its definitely hard to find time. Ive been filming and editing on my phone this whole time 🤣 its definitely a pain in the butt, my brother just sent me his laptop so i still gotta figure it out. Making vids is definitely time consuming and alot of work
@@facelessvaper hey man i just remembered your comment i just did a night ride video if you still wanna check it out. I gotta get a rear shock so the back doesnt sink down so low and get the number plate out of the way but it works great for night cruising
Is there a way to splice the wires from the headlight to wires on the controller so when you turn on the bike the headlights automatically comes on? I mean just bypass the switch cause my headlights is not working with the switch it came with and I don't want to use a switch..
For my controller since its not wired for a head light i would just have to splice the headlight power into the main on off switch and then when you turn on the bike the headlight will get power aswell. Splice the head light power into your bikes onoff switches ground and that should do it just keep an eye on it make sure the light doesnt pull to many amps through the switch and melt it
@@EmxBrandon thanks I think I'll have to go that route..one day I fell and after dropping the bike the switch for the light don't work but that same switch works for everything else like the display..the bike shop told me I need a controller but since it's coming from China it's gonna a wait so in the meantime I'll try your method..
@@trini_boi2414 nah if you wire it right you dont need a controller. But it seems like either your light is broken or one of the light wires came unsoldered from the crash. Hard to tell, but let me know how it goes 🤙
@@EmxBrandon ok cool I'll try tracing the wires and see what's going on and thanks again..
He said butt. jk. thanks for the video!!
🤘😆 no problem!
Which brake ground wire are you splicing into? The wire from the lever or the harness? Thanks
Im not sure what you mean? The wire i cut goes up into the brake lever and then comes back down and into the harness main negative(black) wires.
@@EmxBrandon break lever negative back to negative harness?
@@EmxBrandon I'm doing the same thing right now to my bike, so I'm trying to fully understand the steps so I can perform what you did here in this video.
@@EmxBrandon red to red and black to black?
@@Electronic2wheels yeah that works fine! Technically is doesnt matter which wire is neg and pos on a brake lever as it only acts as a on off switch.
I’m getting the same kit for my scooter, the onboard scooter headlight is 2 wire, not 3 because there is no horn. Is it possible to remove the horn wire and use the 2 pin headlight I already have?
Im sure the connectors wont match but yes you can just put the headlight postitive and ground together and it will work just fine with the button!
@@EmxBrandon thank you! I’ve got a jst connector kit, so I’ll splice the positive and horn(ground) together in a 2 pin connector!
@terpypanda7105 no problem! Yeah thats perfect!
Hello I have a motorized bicycle. What kit do you recommend me getting for it I want the one you have like a headlight, taillight with turn signals,and the switch for it. Please get back to me as soon as you can thanks!!
What voltage does your ebike run off of? I think the kit in the video is a great all around cheap kit that works awesome for 36v-48v set ups and if you have brake switches on your brake levers just follow this video on how i wired it up and youll have working brake lights aswell 😀 the link for the kit is in the description
your link is dead, ok :0
Yeah its been awhile, just search 72v ebike light kit on aliexpress
Hi. So basically the brakes provided the ground? Please and thank you.
The brakes are powered by the main harness and just need to find ground to light up.
Thanks 👍
@@capritorez3793 no problem! Yeah i just cut off all the extra stuff that was coming out of the brake wires and just used the 2 main brake wires. So straight into whatever brake connector you have and then the other side of the connector to ground then when you press your brakes they should light up!
What happen if my controller does not have rear red brake light connector?
You would have to use a 12v reducer and wire your own 12v system. I have a good video on how to make a full light kit that goes through brakes aswell
So the black on the brake sensors is actually the positive? And the red is the signal? I know how to make SM connectors myself. Are you saying I should switch the black and red wires for the brakes? Your brakes part confused the heck out of me
The black is positive yes the red is a signal if you have a controller to plug it into but i did not so basically black just needs to find ground. so i wired the brake plug inbetween that and grounded it back into the harness. If your doing it like me completely forget about the red if you notice later on i cut out the reds all together and only use the 2 blacks for front and back and wired it to one side of the brake plug and then wired the other side of the plug into the harness ground. Making a closed loop when i press the brakes and turning on the brake light.
@@EmxBrandon I do have a controller with 2 brake lines. But when I plug everything in, the brake light is on permanetly when I turn on my bike. So I'm not sure what's causing that, you say the black is actually a positive line and not a ground, so maybe I need to switch the wires around? Also ty so much for the reply
@@DyLemmaOG are you trying to run this same light kit? If you are just wire it up like i did without the controller. Or find the positive wire to your brakes cut it and it should turn them off then just wire the brake wires inbetween. all the brakes are is basically just an on off switch
@@EmxBrandon Yes, exact same light kit. Ooo I could try that. I'll just cut out the positive line from my controller brake lines?
@@DyLemmaOG yeah if that doesnt work just bypass the controller completely like i did 🤙
Please help! I cannot get the break lights to work, the tail light just stays on but blockers, horn and head light works.. what am I doing wrong here? Its frying my brain lmao!!
Unplug your brake connector and wire it up like i did. I think someone else had this problem aswell in the comments. What do you have it hooked up too?
clear as mud for me :( Guess I'm the dumb guy. Thanks anyway.
What are you having trouble with?
does this work with any controller? on my controller it only has a red 2 pin connector for the front/rear lights
Actually the way i have this hooked up it only needs battery power. I just have it connected to my controller pos./neg. To share power between the both 😁🤘
How do I do it on the stock mototec I just want a headligjt
Find a 48v head light or light bar and plug it Into the indicator plug and it will turn on and off with the key! Otherwise you'll need a 12v dc dc reducer
@@EmxBrandon do I need both parts on the indicator connection or do I just sauter it into the connector like you did to your battery?
@Smouh766 youll need the positive wire from indicator to go to the positive of the headlight and negative off the head light to go back to the negative of the indicator. You can solder it or make connectors but you'll have the share the positive wire off the indicator with the battery guage.
@@EmxBrandon I don’t have both sides of the indicator connections though
@Smouh766 the one side of the 2 pin that's already in use is thr positive. You'll need to share that wire.
You took a bird's nest wiring harness and turned it into a black mamba, who does that, you👈😵👍🤷♂️
🤣 thank you 🤘
Extremely confusing and confusing, what kind of controller or do you mean the light switches etc. At least a clear drawing at the end would have been nice.
How you gonna be confused and come in my comment section confusing me 🤣 what are you confused about? All I did was run the brake wire into the brake switch and back down into the main ground. No controller needed, just plugs directly into your battery!
