It's been raining a lot in Buffalo lately so up until yesterday it's been about 8 days since I've riden.

I turned the key to on and the light (headlight) came on as usual, so I fired it up and the light went out. Figured I had a dead bulb so I turned on the high beams and nothing.

So I turned off the bike, key to the off position and fired it back up and both lights are functioning as normal. Worked fine this morning on my way into work as well.

Maybe a sticky switch?

 

Power to the headlights runs through the Starter Switch. This allows for the headlights to be turned off while the engine is trying to start. Your contacts may dirty in that switch, or a common problem is that the solder connection where the wire attaches to the switch breaks loose. The thing that points me to the Starter switch is that neither the High or Low beam were working. If it's working now, well you've got some ideas to help if it comes back.

 

Bump, this now happens freqently, if i flick the switch on and off the lights will eventually come on, anyone have any tips/tricks to take apart the switch/loosening the cables (i see there's two)

 

There is 2 screws that hold the housing together. It's easier to take apart if you remove the Clip-On from the throttle handle. It slides out, then it's easier to work on the switches. I take the Clip-On off the fork tube, split the switch assembly apart, slide the handle out of the throttle, then tilt the throttle out of lower portion of the switch assembly. Put it back in reverse order when you've figured out what is causing the lights to go out.

This is what I do on F3's, not sure about your particular model.
