Ballast or Bulb?
Passenger Low Beam sometimes goes out. Been doing that for the last few months. Any ideas on which it would be? just have to flick it back on to have it come back on but don't want it going bad at a bad time like winter when I can't work on it. Any ideas? Also how to replace it easiest without taking off the bumper?

You have to take the bumper off to remove the headlight housing. Be prepared to spend ~$100 on a new HID bulb if the bulb is bad. DO NOT TOUCH IT with your fingers, wear gloves. If you get oil on it, it will fail.... oil from your hands natural oils. I had a problem where I thought my balast had gone bad. I bought a new one and in replacing it I figured out that I had put the HID bulb in crooked and it wasn't seating. The installation was the problem and the parts were good so now I have a spare ballast.
Anyway, you can test what you have if you swap bulbs between lights and see if the problem moves or stays on the same side of the car.

In any case, saying sorry and thread jacking doesn't make it better. I'd just post a new thread if you have a question specific to your car.

Being able to thump it to make it work is usually always a ballast issue. If the bulb was burnt, it would't work for anything. The only other thing would be a loose fitting connection. So as always, inspect first.

Lol, I one time bought a ballast and 2 HID bulbs (you know how expensive they are if you've replaced them)..... trying to fix my headlight that wouldn't come on.
"Come to find out" I didn't have the bulb properly seated in it's holder so it wasn't making contact at all. Now I have spare bulbs and ballasts for when I need them haha.

It happened to me in my old car (00 Acura TL) where the light went from pure white to yellowish with a hint of reddish purple in the reflector housing. It was very noticable and it happened rather quickly, over a period of 5 days
Now if you buy brand new bulbs, and one is a different color, that's usually a sign you have 2 bulbs of different Kelvin temperatures, aka different colors

I have driver side bulb replaced and the the low beam does not work. It work some time there no certainty that it will work.
I was wondering ballast is bad, if so is it good practice to replace both drive and passenger side replaced. Also I was wondering if anybody has replace whole headlight both side to simple halogen type to avoid dealing with Hid and ballast for long terM.
