Talking xenon headlamp

My driver side xenon head lamp burned out. I removed the bulb and discovered that the bulb housing was melted. The bulb looked uncompromised. However I am afraid that the $100 replacement bulb will flash and burn also if there is another issue. Where is the ballast and how do I inspect it? I did clean the socket where it also appeared to be blackened.

Any photos of the said burnt bulb & socket?

NOTE: You should never handle these xenon bulbs (glass portion) with your bare hands. Any oil/sweat/grease that come into contact with these bulbs will cause it to crack/burnout prematurely.

Question Novice

I was unable to locate the ballast that looked like ones I saw available on ebay. Is the ballast black in color as opposed to metalic? Can I not see it because it is mounted behind the headlamps assembly? I uploaded shots of the ignitor and the melted bulb.

Looks as though you had a short or small fire. I don't know why that happened. But you got lucky.

Do you have OEM xenon headlights? The ballast is screwed into the headlight housing at the bottom and is silver.

From the looks of it, there was definitely a short of some sort.
I wonder if your headlight housing is secured in the back > there should be a water-tight covering/cup that snaps into place to seal off the backside of the unit. I noticed there's lots of rust on one of the bolts in your 3rd pic, so if your car has been submerged or water has gotten into the xenon housing it could have caused your connector to burn/short.

I would lean more to thinking the igniter or the ballast failed. My money is on the igniter. Why don't you plug that bulb into the igniter on the other side of the car to narrow it down a bit.

I have had a hard time getting an "01" igniter off ebay with a two prong connector the same as the faulty one on my "01" 330xi. I have a 3 prong igniter. Can I adapt that to my vehicle.
