Had a 1975 Merc a few years ago and I swear the Bosch headlights were original
You have late Bosch headlights, in Europe they came with plastic diffusers, ZKW headlights and Bosch headlights with projectors had glass ones.
Definitely not the most popular choice but I had beat oem headlights and couldn\u2019t see a damn thing and you\u2019re not gonna catch me spending $500+ for bosch\u2019s just to be oem+ that don\u2019t improve visibility. Honestly pretty happy with the look and I really like the taillights.
Ended up finding someone on marketplace, set me up with a solid used set of Bosch headlights for a good price.
Nooo. Return them. Get the DEPO headlights. Good ZKW/Bosch sets are expensive nowadays and DEPOs are perfectly fine.
For what its worth, I had the Helix headlights on my 2017 GSW and yes, I had to set those up with HID ballasts and HID bulbs. I was able to tuck the ballast inside the back of the headlight and put the bulb access door/cover back on for a pretty clean install.
Just installed them, will have to see how they work out.
Just finished the install and I have noticed 2 things on this Helix unit. 1. When the low-beams are in use they seem to run at a lower power. 2. When turning on the high-beams it also makes the low-beams run at their apparent normal full power.
I think they're shit. The tabs started snapping off a light as it was sitting on my kitchen table.
I have bosche oem lights and they have very poor performance at night.
