So the right headlight went out on the 240 a couple days ago. I tried pressing on the connector under the hood, because I've had one come loose on me before. No luck, so I stopped by the local Kragen and picked up a Sylvania Silver Star for a replacement. Since yesterday was my birthday, I had a few incoming phone calls from family and friends after work, and afterward it was getting late, so I didn't install the new light until this evening. Pop it in-no luck. Tried the high beam and it worked. Then I remembered that Mercedes engineers like to wire lights in odd ways. I pulled out the book and found that indeed, the left low beam, left high beam, right low beam, and right high beam all go through seperate fuses. I pulled the cover off the fuse block and inspected the appropriate fuse. Not blown, but corroded. I replaced with a fresh one, and suddenly all was good.

Moral of the story-always check the fuses first.

I did the same thing a few years ago, so I had a spare headlight waiting. About a month ago it acutally burned out, and I had one to put in. But I checked the fuse first. Live and learn.

It's pretty smart to separate the headlights into different fuse circuits. Who wants all the lights going out at once?
