  • High beam flashes when turned on

    Last night riding home switched to high beam and light started to flash. Low beam works fine.

    check the bulb plug on the harness for loose or burnt wires or burnt connector. If they are all OK remove the bulb from the headlight buket, plug it in, turn it on and shake it. If it blinks replace the bulb

        Checked wires, all good. I found a what looks to be a senser plugged into headlight. Unplugged that and low and high beams work fine, but I lost my passing lamps. I suck at electrical stuff. Looks like that senser has 2 wires run to it. Anyone know what that senser does?

          Could be a flasher unit used to make more visible to oncoming traffic.

            Those have a light sensor to keep it from flashing after dark. If it is a flasher unit it sounds like the light sensor is bad

          Thanks for the responses. Got it figured out. Unplugged sensor. Everything seems to be working just fine.

            Was it dark when it was flashing? If it was still light outside the unit was working correctly. I have one of those units on my bike. Those units are about $100. Ya might want to offer it for sale if you aren't gonna use it. Mine is a Kisan brand headlight modulator.

          Headlight modulator was my first thought, but I'd assumed you knew it had always done that... Oh well, mystery solved.
