My passenger healdlight will flicker when I turn them on, and eventually go out all together. I can turn the lights off and immediatly turn them back on and it will flicker and go out again? Would this be the bulb??
Thanks

 

Easy to check...swap the bulbs around (left/right) and see...

 

i had that happen on my s2000 and it was the bulb.sooner or later it will not come on.

 

Replaced the bulb, still doesnt work? Any suggestions?

 

the balast is most likely bad.you need a shop manual to trouble shoot.

 

What is the ballast?

 

The ballast is just like ones in your florescent shop lights. It jumps starts the HID bulbs and keep a steady current to them.
