i have an electrical problem with my bike, the brake light stays on, ...but only when the sidelight or headlight is on. when the lights are switched off, the brake light functions as normal, any ideas on whats causing this & how to fix it
it sounds like the earth to the bulb holder for the rear light isnt good and the tail light is back feeding through the brake light element and therefore lighting the brake light up.just try giving the bulb a new earth to see if it solves it run a new clean bit of wire from the side of the bulb and onto a clean piece of metal on the frame or the earth side of the battery.
