Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
HiCustomer are both your high and low beam lights out? Do you know if you have Xenon headlights?
Ok, which fuses did you check? Did you check the fuses at the left end of the dash? Do you have a test light or voltmeter? When you say "big headlights" are you referring to the ones in the picture?
Ok, the next step would be to inspect the actual bulbs and connectors. You should probably purchase a new H7 bulb and just substitute one. Mercedes also had a problem with the connector to the bulb overheating and melting. I've attached some pictures that should help. Let me know what you find.
Yes, under the hood is the main fuse box. It looks like the only fuse we're concerned with is fuse #3. Here's a list of Bosch Car Service Centers in MS. It doesn't look like you're too convenient to any of them. Maybe Gulfport?
