No headlights, no low beam, no high beam, no lights

WD-40 is good for a limited number of applications. It leaves behind a lubricating 'mess' that works as long as it is not in a dirty environment. I use as it's name suggests, as a Water Displacing agent, or as a penetrating lubricant. And only where it can be wiped off or is in a 'clean' environment.

I NEVER use it on guns. A gunsmith friend calls WD-40 his 'gold mine'. He has had more work on guns due to use of WD-40 than any other reason. It really gums up triggers and especially revolvers.

Get the lube for the purpose you have. Use contact cleaner for switches (be careful of paint as some can destroy it).
 
Had the same problem. It turned out to be my starter switch at 7800 miles. The service tech told me this is common in Honda's. The contacts just needed to be cleaned and to keep an eye on it every so often. I do ride year round in wet conditions very often.

I realized how importat that little bulb in the headlight housing is. It may be dim and not light the road in front of you but does give you some visability to be seen by others if you headlights do go out.
 
Try "Corrosion Block" instead of WD-40. Available in Marine stores everywhere. Designed for contacts in the marine environment. They make little spray cans like WD-40 as well. Been using it for years. Saved a TV that got doused by a wave.
 
First answer should be starter button... Flip it a few times. No headlights, low or high will work if it is not making contact. If this is dicussed in other posts forgive me. That is likely the culprit.

Seems like that's the most common cause of that problem, doesn't it?
 
old thread, but info is here. @191,050 miles had to replace starter / kill switch housing. lights only work about 20% each time I start it. also high / low beam is failing to work. so I replaced both right and left housings with the leads that plug in on left side connector group at tank. Honda didn't make a small switch to replace inside of housings, have to buy whole thing. I have sprayed contact cleaner before and currently. if I didn't have my extra dual 900 lumen LED driving lights to help me when switch didn't turn on, I would have to leave bike at home.
it was tough to get throttle cable off / on , but patience and trial and error got new one installed. now ready to take it to 200K
 
I had this same problem. Start bike, no headlight, low or high beam. Checked fuses, cleaned contacts in starter button, no love. turned out that the post on the starter switch that attaches to the headlights had broken off. Soldered it back on and not a problem since.
