Hi all. One of the low beam hid bulbs on my 1998 E430 has turned a brownish/purple. I'm not familiar with hid. Does this sound like a bulb problem or could it be the ballast, etc? What should I look for when buying a replacement? Thanks

If you haven't already, go to Daniel Stern Lighting web site and read what he has to say. It won't solve your problem, but might give you insight as to why they should be removed completely, and use the H7 65w rally bulbs. Better lighting = better driving.

Swap bulbs left to right. See if problem moves. Voltage there can reach 25,000V. Make sure lights are off.

Another HID Question

Another thing, there is moisture that collects in that light. Could that contribute to the problem? Is there any solution other than replacing the whole light unit? Thanks

BTW: These are the optional MB HID low beams

Vincent52100, I have a similar problem with moisture collecting in my low beam housings. Short of un-assembling the entire headlight unit, and un-sealing the low beam housing, I would love to know if there is a solution to this problem is.

On the list of options that the car came with, on the window sticker that shows the price of the vehicle and its options, such as the rain sensitive wipers, it also lists HID low beams.

I may have found the source of the moisture. One of the clips that holds the sealed cover on the back of the lights was missing. I found it below the light where someone had dropped it. I'll see what happens.
