All you have to do is put a screw in the little ear on the end of the lever and file it down until you get the light to operate properly. It use to be a real common problem in the mid-to-late 90's models. That little ear almost looks like a casting on the end of the lever they forgot to machine off, but it's there for a purpose.

Another case of a $20,000-plus bike with a designed component that looks like an accident. You can make sure which switch is causing the problem by just un-plugging one of the leads off your rear brake-light switch. That will kill the rear switch and cut your trouble shooting in half.

I have checked the bulb, and actually replaced it, but still no brake light. No light from the front lever, or the foot lever. Checked both switches, and nothing seems to be wrong. Checked fuses also. I put a test light on the mini harness to the bulb, and no signal is getting to it. Help please.

Hope this helps everyone with this BS problem harley had failed to fix over the years.
