You are correct... if the Wing is like my other Hondas. The main power for the left hi/lo beam switch runs through the starter switch. I had to replace one on a VTX... never had issues on the Valk.CMABob said:I believe there is a circuit that cuts off the headlights when the starter
is engaged. The purpose is to direct more current to the starter. Then
when the engine starts the headlights come back on. I don't know the
details of how that circuit works. Probably a relay. It sounds like it may
be malfunctioning. I'm sure others on this site will have more details and
perhaps a fix. Blessings.
