As others has said it looks...... tacky. The led's just give me the impression that the car has eyebrows. I personally would not do it but led's seem like they only work in a select few cars. For me I'm on so-so with your car, I just can't get of the idea of eyebrows off my head when I see that.
I think you did a good job of putting them in a good place for a car and the installation looks pretty decent.
I have thought that those Audi lights have looked stupid on anything other than the R8 though. Sure, they were kinda cool on that car but it's lost all of it's appeal now that everybody and their mother has it on their brand new bargain basement econobox.
I'm not a fan of these LEDs... And also as others said, tacky. I really thought it should be something special in an Audi but now it just gets everywhere! Now I can find those things in a car accessories shop.
They look kinda wierd on top, also wierd on an S-class, but definitely not bad. I wouldn't do it, but then again I'm kind of conservative when it comes to mods.
Its not for me, looks really bad. Its fun to see car like Mercedes Vito or some Civic with this kind of useless gadget. And you have got S Benzo... Sorry
Meh, I don't think they look too good on/in the headlights. But I'm sure if you mounted them lower down, maybe on the upper edge of the vent that houses the fog light
