ARE U GUYS TALKING ABOUT THE REAR FOGS THAT COME ON THE RIGHT SIDE OF THE CAR FOUND ON AUDI'S AND MERCEDES. IT JUST LOOKS LIKE THE BRAKE LIGHT IS ALWAYS ON THAT ONE SIDE BUT WHEN U STEP ON YOUR BRAKES U CAN TELL THAT THE ONE SIDE IS BRIGHTER. I THINK THIS IS WHAT U ARE TALKING ABOUT. THERE MIGHT BE JUST A PLUG TO PLUG IT IN. MY FRIENDS AUDI HAD IT AND PLUGED IT IN AND IT WORKED, LOOKS COOL AT NIGHT. HOPEFULL THIS IS WHAT U GUYS ARE TALKIN BOUT.
