does one exist on here?

did you try searching? that'd be the first thing to do.

then second i would trying doing it myself, and making a DIY if one does not exist.

most 320's already have the fog light switch, but no fog lights, just buy a couple, wire em up to the switch, and bingo you have fog lights

not on here or anywhere from what i've seen since most want them off

I'm pretty sure I wired my aftermarket fogs to the fog switch. But my car came with them. Did your's? Or is THAT the problem?

thanks. mine doesn't have a switch. i'd have to buy one, plus the lights. I don't even know if my bumper has the holes, i'd have to drill those i suppose if they aren't there. i probably will say screw all this. but thanks for the help anyway. it's just hella foggy in my neck of the woods. visibility isn't very far. i was outside last night half asleep and the fog was heavy

fog lights are super easy to put in. you can get those ones from the local super store for 20 bucks that look like the ones that came from the factory and the wiring diagram is in the package. it takes about 20 minutes to put them in
