My right headlight is dimmer Than my other light and goes out after a few minute. I'm assuming I need another bulb? I have the AFLS and how much would a bulb be?? Thanks a lot!

 

Switch bulbs between sides, and see if the problem jumps to the left headlight. If it it does, it's the bulb. If it stays on the right, it is something else, probably the ballast.

If it is the bulb, most people replace them in pairs, or you risk different color and light output.

Any D4S bulb will fit; stock is 4300k Philips or Toshiba-Harrison, some people prefer a whiter/bluer light and opt for a bulb with a higher Kelvin rating, even though the 4300k gives better illumination.

 

I have this issue with my 08IS350 light will go out couple minute. Find out the problem was bad Ballast.

 

what part are you in CA? If you're close to me, i could help you out. I have extra set of Ballast and bulb to determine what problem you have
