Over the last year I have replaced three headlight bulbs because the low beam keeps burning out or so I thought. Replaced two bulbs in the past week as the dealer told me they would have to keep the bike one to two days to diagnose all of the electrical.

Today, I opened the bucket with the power on and moved the wires around and the low beam which I thought had failed lighted. Works on high beam also. So, instead of having a serious electrical problem I most likely have a wire that has a bare spot and should be able to fix that with a bit of electrical tape. At least, I hope that is the problem.

However, due to the failure(s), I went to WalMart and bought a new bulb which I will keep in the saddle bag which I feel is really cheap insurance should a bulb actually fail at night. Of course, I would get to a safe spot before working on the bike at night. Just thought I would share the idea.

A bare wire contacting where it shouldn't would cause a short circuit and blow a fuse. What you are describing are the symptoms of an open circuit. A connection is not being made properly. A marginal connection often shows a discoloration in the area from excess heat. Check your connections.

I had problems with the electrical connections of my ST2 headlight. I finally took the whole assembly out and cleaned it up. I added solder to a couple of spots to make better connections. I no longer have problems keeping the headlight on. The low beam is still one of the worst headlight designs I've ever seen, though. Fortunately I almost never ride at night, so it doesn't matter that much.
