W210 highbeams fixable? - PeachParts Mercedes-Benz Forum

Hmmm... if the H7 bulbs are truly extreamly bright, my suspicion is that they are not working. When I picked the car up from having the aiming done, the tech showed me what was going on against a wall. What was happening when the highbeams were turned on was that there were bulbs being lit, but they threw hardly any light and that light was of a weird pattern (a couple of rings of light rather than beams.) There is always at least one bulb lit in the highbeam enclosure. As he had little experience with MBs, he was not really clued in to what the problem might be, but was guessing that the reflector was somehow damaged and so the output refraction was somehow skewed. So, if I understand you right, the H6 bulbs should come on along with the H7s? Also, I've noticed that the H7 comes in a highbeam and a high/low beam. Is this application strictly a highbeam?

Ah, well it could be many things here, from a burned out bulb, to defective, to the wrong ones, to the fact they could be sitting in the bottom of the lamp assembly versus being in the sockets.

So an easy test given you've two H7 bulb in the assembly is to follow the instructions in your owners manual and swap the bulbs when they are cold. Don't touch the glass. Then try it and tell us what happens. It will also give you a chance to confirm if the bulb is correctly placed in the housing.

Had a similar problem (misaligned headlights) when I bought my E320 back in '05. Turned out the problem was the previous owner had not installed the LOW BEAM headlight bulb properly (it was kinda cockeyed in the housing's socket - not seated properly). When I leveled the low beams, the high beam on the "bad" side was looking at the International Space Station. I suffered with it for a while until the misaligned headlight burned out and discovered the problem when I replaced the bulb myself.
