Mine dont work for some reason, anyone know what fuse theyre connected to?

I had this with mine - it was just a bad connection with the bulb/bulb holders. Try taking the bulbs out then refitting them (the bulb holder is just a bit of bent metal...!)

Ahh of course, ill give that a go tomorrow tah. Would this affect both of them?

 

Well........... I had the right one go one week, and the left go the next - so I fixed both at the same time.
If both of yours have gone off at the same time, it would be an amazing coincidence if the bulb holders were at fault !!!!!!! -- However, its easier to take the bulb cover off and twiddle with bulbs, than look for a wiring/fuse fault..............
