Hello, I have a 2007 road glide and I do NOT have a tail light when the bike is running and when I turn the right or left turn signal on ALL the lights on the back come on flashing, if I hit the brake lights they ALL flash brighter, if I turn off the signal lights ALL the lights stop working inclucding the brake lights ...I have checked ALL the fuses and relay and I have NO idea where the flasher is for the signal lights there is a circuit board in the rear tail light and I am wondering if that would cause this nightmare I am having any help is appreciated ...I am sure someone less has had this problem wiring nightmare...

 

If your bike has had a lowering kit installed, jack the bike up using a frame jack, and when the rear wheel is off the ground, use an inspection mirror to check if the wiring harness which runs under the fender has any exposed wires and/or broken wires.

I helped someone with the exact same problem and it turned out to be caused by wires that were damaged as a result of lowered bike wheel rub.

 

Ok thanks I do have a lowering kit on the bike ... will check it out

 

Ok it was NOT the lowering kit that created this when I bought the bike it has a 3rd party cable on the cable to the rear fender and to my lights and brake lights it used to bring the brake light on and off and then on I got rid of the the cable and put it back to factory .. works great thanks all ...problem solved ......
