Just solved that back light problem mate was to do with the brake peddle.Weird one mate.
Hard to say if they are related but the brake lights are operated by the brake light switch on the brake pedal. Might be worth a look at the switch and the wiring in that area in case something is broken or out of place.
Also check your fuse boxes (interior and engine bay) to see if anything is blown.
