Tonight I notice that one of my headlights is dimmer and purplish colored. I assume the bulb needs to be replaced. Why do these not just burn right out and what is a good factory replacement bulb?

Likely the ballast is going out, try swapping the bulbs....if the known good bulb is dim you will know that is the issue.

Is the ballast hard or expensive to change? Looking in the manual it says they are xenon headlights. Is this the same as HID? It also says there is enough juice to kill me and I should exercise caution and have the work done by a qualified person.

I called the dealership and it's the bulb. $296.50 plus 20 minutes labor to replace ($50.00) and taxes. I ordered one from NAPA for $104.77 and it's supposed to be OEM. No mark up there on parts. I assume as long as there is no power to the lights (switch off) it should be safe to change. There is a 25,000 volt warning sticker on the lights.

$300 dollars for a flooking headlight? Awesome!

My GF always throws a fit when one of these HID equipped vehicles is behind us on the highway. LOL

F it. I just drive with my high beams on everywhere I go now. ;)

Xenon are conventional bulbs, using a different gas, to give off a whiter light than halogen. H.I.D. stands for high intensity discharge, using plasma, super exicited by high voltage delivered by ballasts to give off light. No filament. Unless you buy good quality H.I.D. systems like PIAA or such, and cough up big dough, expect problems. If your vehicle came with an aftermarket, no-name HID kit, pull it out and return it to conventional bulbs. If your bulbs say xenon, they are not a HID system, swap the bulbs: $40.

2006 BMW 530xi. It's a nice car to drive. I had to buy some power steering fluid for it and the retail price was $71.00 a litre but the guy gave it to me for $50.00 plus tax. Some synthetic stuff made in Germany and it's all I can use. Like I said, nice to drive, but not to fix. That being said, if I ever had to get in an accident it is one of the vehicles I would choose to be in.

Not that anyone really cares but I took some pics and am going to tell the tale of my Great Headlight Bulb Changing Adventure. I popped the hood and this is what I'm looking at.

4 torx screw and a little wiggling and it's out (after unplugging two sets of wires). That's the wind shield washer reservoir and it looks like they use a lot of aluminum in these cars.

I popped the back off to get at the bulb. It has active headlights which are really nice for night driving but I don't think it would be cheap to replace.

The bulb.

Yep, she's burnt.

Put it all back together and it works. Surprise surprise. With the lights shining on the wall you can see a light purplish tinge on the old one so I imagine it will be going eventually. I think they are rated for something like 27,000 hours (or maybe 2700 hours). I know with halogen lights in my other vehicles I have changed them in pairs, but they didn't cost like this either.
