Sooo, why did BMW put a duel filliment bulb in the rear, yes rear, of the taillights for a rear fog light setup and how do I get the darn things to work? There is no fuse, nor wiring for one, in the fuse box, Position 17. My last thought is to scab a wire from the front ones and tie it into the harness in the rear. Someone has to have a better way than that.
