Headlight repair on 2003 Mercedes Benz E320

Yes check the fuse, it could be a bad connection going to the headlight which may also blow the fuse.

Check the HID ballast. Make sure the ballast is not blown.

You most likely need a new low beam headlight BULB.It has the low and high beam in it and the separate high beam has only high.
You SHOULD have 2 tabs ,one at each end to pull up and the headlight assembly should then come out easily.
Tapping a blown out headlight can reattach the filament for a short time but after that replacement is necessary.

HEADLIGHTS NOT WORKING

It can be faulty headlight switch or issue with its wiring. Or its faulty head light fuse.

Thanks.

the bulbs are changed from the back side of the light housing

if you can get the clear part separated from the backing you can polish this clean. It takes a little bit of skill and concentration and patients but it is possible

how do you replace the low beam lamp on the 2005 E320?

Thanx.

Sit down outside your front wheel by the side marker light with a stright screwdrive and gently pry it off back toward yourself. this assembly will flop out to you. won't get to it any other way....low beam ? I have not replaced one yet. got you halfway there. don21093

Purchase the correct bulb, open your hood, unscrew the white retaining ring behind the non working lamp when loose turn black connection 1/4 turn counter clockwise till tabs line up pull straight back remove old bulb put on rubber gloves or BE CAUTIOUS NOT TO TOUCH NEW BULB GLASS WITH BARE FINGERS. Oils from your hands an cause bulb to heat unevenly and cause new bulb to explode in the headlight assembly
So with gloved hands open new bulb insert follow steps in reverse to reassemble. Happy Motoring
