pic6 - "6" cut line shown, use dremel to cut.

pic7 - use long nose pliers, bend the "2" blacked out pieces of the lip down flat & use dremel to cut/remove completely.
- than use long nose pliers, bend down flat the "4" white pieces of the lip.

pic8 - final result. touch up with paint to prevent future rusting.
- repeat process for the other end.

pic9 - overlay on template to verify.

Wow, thats a lot of work compared to the W126 fog swap. But worth it. I really need my fog lights.

Do you have to heat the assembly to open the housing? oven?

Nice work Fred! VERY creatively done.

No heat/oven required.

There are 4 locking tabs on top & bottom. Just pry (CAREFULLY) with flat head screw driver slightly to release, the complete lens assembly will come out.

Thanks Patrick. It was either french euros or no euros at all. ;)

Are the Depo or european Bosch all set up with clear fogs? My us light have the yellow shields as oem. Should I assume the euro or Bosch are all without the yellow shields?

Thanks.

I'm not sure but you can take the shields off if you don't like it.

Like Ismalley said, you can remove the yellow dome shield.
This yellow reflector might be a "direct fit" (no mods required) for your us headlights (not 100% sure).

" This mod is ONLY for euro Bosch headlights "

Euro Hella headlights have different mounting bracket, not sure about Depos.

Only euros from France have the yellow reflectors from factory.

wow,you know when i was installing my fog light bulbs into my depo units, i dont recall even seeing a reflector,all i saw was a black plastic teepee shaped thing in front of the bulb.how odd,now that i think of it how will they reflect and work correctly if they dont have built in reflectors,i guess i will just wait and find out when i install them,i bought 55 watt blue fog light bulbs.i figure i wont be using the fog lights to often,i know the color is illegal well i think its for offroad use only.if i purchased white bulbs im sure they would just add to the brightness of the headlights being to bright asnd most likley getting harrased from the police,we will see what the blue fog lamps look like.

also,does anyone know what the giant white round plastic thing is behind the headlight assembly,it has a vacum tube attached to it and there is a nipple on the headlight unit near the electrical pin configuration,im not sure why its there or what it connects to,anyone know? this is on the new depo light units

For headlight "height" adjust via vacuum switch.

These aren't euros but......
 

Interesting how the lights create a sharp distinct line and these are my stock bosch lights, but my low beams or high beams don't. Is it just the casing?

Anyone know where these yellow reflectors are coming from?

They're in the OEM lights.

Well, the OEM fog lights have the yellow "bubble" or whatever it is around the bulb, but the reflector is still silver, isn't it? Where are these yellow reflectors coming from? The ones that require modification to fit the W124 housing?
