I did a search and couldnt find the answer I was looking for, i was thinking on doing the one peace headlight upgrade to my 99 a4 but i have the fog lights in the headlights themsleves, dose the fog light get bypassed with the new lights, or will i still have the use of them.. was looking at the ECS tunning lights and a pair of Halo's made by JDM cant find the answer anywhere..
