Hi i have bought my first car the other week and only just realised that my reverse lights dont seem to be working, i have changed the bulbs checked the fuse even had the reverse switch changed to no avail. what am i missing, could this be an earthing issue? i think this but then i also think that the brake lights are working fine, so if it was an earthing problem surely it would affect them to unless they are on a different circuit? Anyone with any suggest please, i will be more than happy to try anything. thanks folks
