Hello everyone,,
I have a 2002 S430. When turn on the headlights, the light beam moves up, then down and stops in the center. I assume these are Xenon bulbs. However, when I first turn them on, they are both bright white. After they warm up, about 2 or 3 mins, the right one has a very slight pink tint. I am assuming this would indicate a possible failure coming in the near future. I would like to replace the lamp, but I don't l know the type, or number. Its a job taking the headlight out, removing the lamp and then putting it all back together so I can drive to town and get a new bulb. I don't think these bulbs have been replaced since new so how is a good way to find out what I need reversephonelookup.onl/ curated.onl/nba-reddit/ pcbuilder.onl/pcpartpicker/? I have also read in this forum about replacing both lamps at the same time, others say you don't need to. I will just start with one and see how it matches up with the left side first. My main question is, what is the best lamp to replace it with and is this a lamp that is available at most parts stores or MB Dealers only?
Any suggestions would be appreciated..

It is xenon. The question is if you have already the lens type Bi xenon or the regular xenon, which was standard for the pre face lift models. For these models you need to buy D2R burners. Important is to replace both sides. These burners are standard items, no MB special. But buy good brands such as Philips or Osram no cheap Chinese imports, they tend to start flickering after a short time in service.

Many auto parts stores don’t sell the d2r bulbs and yes you need to replace in pair for matched light color

i recommend rockauto.com they have many choices from $20-60 each . And they will be genuine bulbs . eBay and Amazon sell fake bulbs even if listed as genuine because they use third party sellers
