: xenon headlight not working ??

i have a 2003 ext ... the other day i started my truck and noticed the driver side headlight was not on... i have the factory oem xenon headlights on my ext... when the headlights are turned on .. the passenger headlight attempts to turn on you see the xenon light coming on but it doesnt reach its full brightness and then just shuts off ... also while it is attempting to turn on you hear a slightly louder than usual buzzing noise i believe from the ballast ?.... doesn this sound like my ballast has gone bad or could be the bulb ?.... even used these ballasts are on ebay for about 120.00 not too cheap !

any suggestions or help would be apprectiated !

sorry correction even though it might not be a difference other than the room accessible under the hood to the space behind the assembly it is the driver side headlight

I would say ballast for sure. You can double check by taking the OEM bulb you KNOW works, and swap it with the problem one. If the result is the same, then ballast, if the bulb works, then bulb.....good luck.
