Question Help with rear fog activate

I've been doing some research on how to do this and I think it is possible to do a rear fog light activation on a US facelift coupe, but I'm not entirely sure how (I seldom tinker with the Bimmer). There are a bunch of DIYs regarding prefacelift models, but nothing after.

I have a 04 330ci and was hoping we could get a thread started for those who want to use these, in my area they would really come in handy and I'm sure more people than myself would like to do this.

Here's a link on the forum to one of the very few helpful threads:

Anyone have any suggestions?

Ah phooey...



I feel like a blundering idiot every time I start a thread around here. Turns out not only would a facelift model need a new faceplate for the LCM, but need to have new wiring to the rear end of the car as well as having the car re-coded.

Are you trying to make them function as actual rear foglights? I wired mine as 4th brake lights. But it would t be that hard to wire them with the license plate lights and make then turn on that way

I'm thinking of making it so they function as normal rear fog lamps. Where I'm from they certainly would come in handy for weather conditions and for when I get a tailgater. I agree I could wire them to the license plates lights, but I don't want to have them going on without my control.

For brake lights... Idk... Halogens and LED don't mix too well.

That looks phenomenal! How'd you go about it?

I think when the weather gets warmer I might make a DIY on this when I finally get this done.

i followed this diy. and i used a red SB60 1156 bulb from ddm tuning claimed to 420 lumens, almost perfect just a tad bit dimmer. im going to guess you already have the correct bulb carriers.

Ahh, I was under the impression it was the 1157 bulb type, but for all I know they could be essentially the same thing.

I don't quite have the correct bulb carriers, I'm gonna have to drill the metal plate off in the housing. But I'm really enjoying your M, it looks amazing. Thanks for the link too.

the difference is 1157 has two contact points, the 1156 is just one. just be careful when you drill, i accidentally messed up mine by pressing too hard, thats why i bought carriers instead. probably better to have the drill go fast but with light pressure.

here are some more current pix. i changed the trunk lid lights with the prefacelift style but kept the larger facelift lights. then i smoked the clear parts. looks better imo because it keeps the lines going and the L shape BMW's normally have for lights.
