- Toyota Prius headlight ballast replacement 2004 2005
I have spliced many wires over the years. I chose not to attempt to splice this high voltage cable.
Why? The HID output is a high voltage -- maybe 80v? maybe higher like 25,000v to start the arc:

Those voltages are well beyond the typical 600v rating of normal splicing methods -- certainly beyond the rating of simple heat shrink. In addition, Toyota went to a lot of effort to shield the wire with an external metal braid.
For these reasons, I chose not to cut and splice the wire. That I why I made the video.
It is a bit of a challenge to get the bulky shielded high voltage connector through the headlight housing around the reflector so you can either replace the ballast (although the 2004 and 2005 ballasts last a long time) or, as in my case, move the working ballast to a new headlight.
I watched Auto Buddy's ( / @autobuddy7985 ) video
• Toyota Prius headlight... and tried to follow their instructions. I finally got it but it was a struggle. I hope this video makes it more clear that it can be done by removing both pieces of the adjuster.
Sorry for the crap video work and non-existent editing. It's really what you expect from a small unmonetized channel though, isn't it?

Thanks - your part about removing the plastic piece that holds the adjustment screw helped. It was indeed the hardest part of the job... Well... Besides trying to get the protective cap off. I broke a plastic piece off each side trying to remove the dust/moisture cover. That was terrible! Maybe some silicone applied to the gasket will make re-assembly better!
So toyota must expect the entire headlight to be purchased which should include all of the bulbs, etc. My symptoms were flickering and then the main light would just go out. Turning the lights off and back on would restore the light for a period of time. I swapped the HID bulb to the passenger side, but the problem remained on the driver side. I ordered new bulbs and a ballast. I am really hoping this fixes the issue!
Just checking to see if this fixed your issue? I have the exact same problem and just purchased the ballasts online. @@skipdog77
The symptom of my bad ballast was the the headlight would go off but come back on if I turned the lights off and on. Finally went out completely. I think it's really helpful to remove the metal cover at the high voltage connector and then put it back on when you're finished threading it through. It holds the shielding to the plug but can easily be removed and put back if you're careful.
I think I also had that symptom with bulbs getting old. A lot easier & cheaper to replace the bulbs -- if the problem goes away then the ballast was good. If you end up having to replace the ballast, then you also have new bulbs :-)
In this 2005 Prius, I wanted to replace the headlights (horribly foggy) but the 18-year-old 2005 ballast is still going strong, so I moved the old ballast into the new headlight.
@Baxsie you're a lifesaver. Well, a time saver. I am having same issue and wasn't sure if a dying bulb would cause this. It seemed to me like it would but have had people telling me it was in my switch or something because bulbs just die or flicker on and off. I was more for the having to turn it off to "reset" it theory myself though. So, thanks 😊
@@Baxsietip for foggy headlight assemblies - put some insect repellant spray on it. Then use a rag to polish it rubbing it off until it's clear. I was shocked when someone showed me that
Great video. What i found easiest to do is take metal cap off and gently push through the housing and it will slide right in. I used little amount of wd40 and then cleaned up after getting through
Nice. So many ways to skin a cat :-)
😡😡😡😡 the person that designed this headlight assembly and balanced unit, belongs in prison for crimes against humanity 😂😂😂😂
This is one of those jobs you just start with taking sandpaper to all your knuckles
In theory, the ballast would last the lifetime of the car --so I guess they did not think of it being replaceable. But I think 2006 and 2007 had some bad batch of ballasts that died on a regular basis. I think after, that they switched to halogens. My sister-in-law bought like a 2007 and they ended up selling after several headlight failures. I was always ready for my ballast to die in te 2005, but 18 years later I'm moving it to a new headlight instead.
I agree with you - this is a knucklebuster.
It is such a pain to change that ballest
Yes. Hard to believe that Toyota never revised the housing to make it easier. #oldcars
Curious about what the ballast does ? How do you know if it's bad ?
The ballast is essentially a high voltage power supply that boosts up the 12 volts from the car to some very high voltage that will arc inside the HID light bulb. I'm sure there are a lot more details than that. Maybe google HID lighting system.
I cut and spliced with high temp connections. Easy.
Read the title!
@@defaultname8587 I did splicing was easier. Less head ache . I'm an electrician. and faster
There are valid reasons I chose not to splice the cable. I have updated the video description to explain why I avoided splicing.
I managed to do it without splicing by disassembling the plug that the bulb connects to. No soldering involved either. You just have to be very careful not to damage the tabs. I practiced on the old plug first.
what about for a 2003?
Sorry, I do not know. I only have (well, had) the 2005.
Is it easy cut wire in middle to take it out and put new one reconnect it. Any safety suggestions?
