2007 Prius lights-going-off issue, some sites say changing the light is short-term fix. (that real issue is ballast) Is bulb replacement lasting?

I've only had them in for about 5 months and haven't had the issue yet. However, my original lights didn't have the issue until after a couple of years having the car.

I've had mine over a year now, and have not had to change it, but I don't imagine it will be too hard when the time comes. Just spring for a CFL or LED light bulb and you will be ready to change the fixture before the bulb goes out.

I had the same problem. I replaced the ballast and it took care of the problem. I also discovered the old one had got so hot it was partially melted.

No surprise. My last one lasted two weeks. These cheap bulbs cause damage to your ballast. Expensive repairs resulted. Bite the bullet and buy the Mitsubishi bulb. Mine lasted for over five years.

in theory it should fix the problem of the tv turning off & on. We replaced the bulb, it worked for a few hours or days (can't remember). then we googled for more help & saw something say that a lot of times you have to replace the ballast as well as the lamp. did that & it still doesn't work. We just decided to buy a new tv & be done with it instead of having someone look at it & pay that charge as well. I am sure this doesn't really help, but that's what our experience was.

It is normal John, mine does the same thing without any adverse effects. Actually, I noticed that after an extended period, they shut off completely. Keep in mind, its not the bulbs, but most likely our trucks that cause it. It just isn't a strong enough current to be noticeable with the standard bulbs.

First thing to do would be to get the battery tested. That way you know if the battery is at fault. If its not the battery it could be a faulty wiring harness, but that's pretty uncommon. The ballast turns on when you turn the headlights on, so if you accidentally left the headlights on then the ballast will drain the battery. I would re check the wiring and make sure everything is in its place. If that's not it then I would ask for a replacement.

Hmmmmm, my lights are still ok, possibly a warranty issue... possibly a defective unit or bulbs...?

You can change it, you can even replace it with HID type bulbs. H3 I believe is the type.

Unfortunately I have had no problem with my HID ballast. Try contacting the manufactor.

How do I received warranty replacement and long is the warranty on the ballast?

Connection might be faulty. Try to see first if your old lights work and if they flicker it will mean that your wiring somehow are burnt up. If they don't flicker then you should do one side HID and the other regular if the either side flickers it means you have a shot wire on the HID side. Do the same but reverse. If it doesn't flicker, then your best bet would be that the ballasts have gone bad. By flicker I mean constant flicker, HID's take a little bit to warm up and will flicker once or twice.

I'm not sure the LED is replaceable but there should be a driver inside the back of it similar to a ballast on a flouresent fixture might be the problem.

after looking at mine a little closer it's as if its 5 little LED lights off together encased in plastic. I do not see a way to replace it no I have ever seen a product like that in the light bulb department. I will say that I've had mine since 2010 and I've never had a problem with it as long as the batteries are fresh. Hope that helps

If by "all my light" you mean the overhead light comes on and won't go out it probably would be the switch. My problem was that I had no dashlights when I was driving at night. I'd suggest getting the new switch and changing it out it's not hard to do.

buy a new unit. for the price of these new if you have a few of the LEDS go out you should just buy a new unit. they are not worth messing with. I have 3 lamps go out on mine after a few hours. they sent me a new one.
