If after you start your Wing and find the headlight isn't working, neither high or low beam or the high beam indicator light, but the fuse is good, the problem is a sticking starter button switch. there are two sets of stationary contact points in the switch one for the headlight and one for the starter with a set of spring loaded sliding contacts between them. The light contacts are normally closed and the starter contacts are normally open. When You push the starter button the headlight contacts open, turning off the headlight so all available unused electrical power will go through the starter contacts to the starter, then when you release the button they close, supplying the headlight with power again. When the switch gets dirty the spring loaded slide contacts will stick midway and not travel all the way back to the headlight contacts and the lights won't work. A good flushing with electronic contact cleaner then a quick spray of WD-40 to lube the button and slide, will set everything right, without taking the switch apart, though you may have to disassemble the left control housing far enough to get the cleaner into the switch housing. This tip may be old news to some of you, but I thought it would worth mentioning, as this problem can be a real headache to solve, because if the bike sets for a while, the slide spring may over power the dirt and the light will work again until the starter button is pushed and the slide sticks again, leaving you without lights.
