Hi guys, The drivers side dipped beam headlight on my Cab keeps failing, this is the third bulb in as many months. It one of the projector style dipped beams so it's a separate bulb to the full-beams, they're nothing special, just normal halogens. It's very annoying because the bulb is an absolute pain in the **** to change, not to mention a little bit dangerous when it happens on the way home in the pitch black (which is about 5pm now-a-days). I have checked over the headlight unit and I cannot see any sign of water ingress, which would have been my first guess, the unit looks perfect. Can anyone suggest why this might be happening? Or have I just been unlucky? Cheers Seb.
