Not sure why but the left fog light on my Verada doesn't turn on. If I knock on it a couple times it flickers on, but if i turn them off then on again it's turned off. If i knock the light on then drive for a half an hour it will turn on if i use the car within half an hour. I've taken it out and taken it apart and checked the connections but they all look fine. Not sure what the hell is going on here :confused: . I appreciate any help anyone can give me. Cheers.

Sounds like a contact corrosion problem - those lights are pretty exposed to weather.
Clean all the contacts again, try those little wirebrushes sized like a toothbrush,
and coat the contact with WD40 to protect them.
