My lights have just stopped working. All the lights. However the horn and cut off switch still work.(They're on the same switch cluster). Its a PITA as to circuit test anything I have to run the engine (no battery). There are no fuses. Its a KTM EXC 300. It was submerged up to the top of the fuel tank in the last enduro, but the lights still worked and I rode for another 3.5 hours. Could it simply be a switch failure?
