My left headlight used to flicker occasionally and went out completely recently.

What's the best way to diagnose this? I hope it's not an electrical issue that involves the replacement of the complete headlight assembly and more of a simple bulb issue.

Assuming it is a bulb issue, what model and brand of bulb should I purchase for it and is the replacement easy enough to do a DIY job?

Finally, it seems the foglights aren't stock. Here are some photos to give you an idea of the setup.

In short:

1) The low beam is yellowish-white
2) The head light is white
3) The foglights are bluish-white

Is this what the stock setup looks like (had to use a member's photo):

And can I buy these to fix the headlight problem?

Are your headlights xenons? If so you might need a D2R bulb, first I would try switching the bulbs from the other light and see if it still does not work. It could be the bulb or the ballast that is having issues.

Finally, the Data Card for my E55, which shows that it did come with Xenon as stock:

Thanks, what other bulbs do I need? Does the headlight have two bulbs? And yes, mine had factory Xenons (data card in previous post)

Each headlight has 3 bulbs, low beam, high beam and the parking light.

This should help.

Thanks a lot, that really helps. I'll get the ballast checked first, and if it's not the problem, I'll get these bulbs, in pairs.

Good news! The bulb from the other headlight worked, so it was a bulb problem, and I ended up buying a pair from Amazon.

These are the ones I bought and they worked beautifully:

The bulb that died was an Osram, while the other side was a Philips D2R too, so it's been stored as a spare bulb now.
