2003 GL1800 has no headlights (high or low beam). When put in reverse, the low beam lights come on and also the side stand light.
The problem was the starter switch. The headlamp bypass that is actuated by he starter button wasn't working. I hit the switch several times Vigorously with my thumb and the lights started working and the side stand light went out.
Dreaded sticky buttons in the dirty switch. Just thought I would pass it along .....
