The passenger headlight bulb is constantly blowing say ever 3 months. All other bulbs are fine in fact they have never blown since I have owned the car just this damn left side one. I always buy quality bulbs never touch the bulb so maybe a wiring problem somewhere or is there a fuse I could check replace. The car is mk2 face-lift focus. As said all other bulbs never blown and not starting to bug the hell out of me.
