Hello Barry,

Thanks for your e-mail.

The fact that your covers are glass and state Bosch H4 leads me to believe they are Euro lights. They will be a single glass lens that covers the headlight reflector as well as the fog lamp. The original W126 lights used a rectangular sealed beam unit that was replaceable. The Bosch headlights use a replaceable H4 (9003) bulb.

If I'm not successful restoring the headlights I just bought (see below), I will give you a shout.

The Mercedes dealer that was doing the inspection won't approve E code headlights. They must have a DOT marking. So as mentioned, I'll use the originals assemblies to get the car through inspection. Once I have the certificate I'll reinstall the Euro lights. I'll keep the originals in case I run into this issue in the future.


Hello T. Walgamuth,

Appreciate your e-mail.

Hello All,

Quick update to let you know I was able to find a pair of headlight assemblies. A chap about 120 km (80 mi), from where I live was parting out a 300SD. W126 are very rare in this neck of the woods so I lucked out. The assemblies were rough but with a little elbow grease I can have a set of usable lights.

To everyone that read the post - thank you for your consideration.
