Xenon headlight bulb keeps burning out

[Kirk325]

The xenon bulb burnt out on my driver side, 2003 325ci, so i replaced it. I turned the switch, and the bulb was fine. The next time I used it, it blew out again. What is causing this?

[LyssaToldMe]

Are you putting in a higher or lower watt bulb ? And are you putting in the right size with no extra fillimants ?

[Kirk325]

I replaced it with the same wattage of 35W, and it is the Eiko Brand made in Korea, which was available at O'Reilly Autoparts. The original was made in Germany by Osram.

[LyssaToldMe]

Hmmm shouldn't make a difference. No extra filaments right ?

[Kirk325]

Nope. I was reading other threads, and it might be related to a bad ground, or problem with the alternator. Maybe I should just drive in the daytime.

maybe the voltages is not enough

might be a silly question are you handling the glass if i remember correctly oil from your skin can cause them to have a very short life

I learned that it's not the bulb. The driver side light works intermittently. It's been doing this for the last several weeks. The light works for a given period of time, such as a week, and then it doesn't work for a few days. Then, it will work. Sometimes I turn on the lights, and the driver light goes off after a few seconds. I switched bulbs with the passenger, but it still did it on the driver side.

Either their is a problem with the headlight assembly, or the wiring. I would remove it and take a good look at the connectors and wiring inside it, and trace the wiring back.
