Hi John:
There are switches at both the pedal and lever that activate the same brake light. Either you are not getting power to the switches, or it is not getting to the brake light (or the brake light bulb is burnt out). Try checking the bulb first, and while you have the bulb out, use a voltmeter to see if you're getting power to the bulb. Then check to see if you're getting power to the switches. I don't know if there is a separate fuse for that circuit, so check your fuses. Odds are you'll have it solved pretty quickly.
Hope this helps.

Rear running light not working on sportster

Hi Anonymous, always check fuses and bulbs first for broken filaments. Then check the connection at the rear fender wiring harness, inspect for corroded, broken or loose pins. Use a dab of dielectric grease and repair as necessary. Check your brake relay if you have one , check your brake light switches for continuity, some models rear turn signals were single filament bulbs only, no running light. If all else fails get out your test light and start tracking the power wire from the harness connection. For a free wiring diagram please visit the website below and good luck:

My tail lights/brake lights wont come on and the signal lights either. But the turn signal will light up when activated. Whats wrong? Its not the fuse. Should i just bring it to the dealership?

Taking your bike to a dealership might be the best choice. If you can't troubleshoot it, I certainly have a time trying to locate a problem without the benefit of being at the bike myself.

When i press on the rear break, the break light does not come on. break light will come on with the front brake engaged. have checked the bulbs.

The rear brake has a pressure switch that turns the rear brake light on and off. If it's working correctly with the front brake, this switch is the first place I'd go to. Make sure the wires a firmly plugged onto it.

You can find the switch by following the metal line that comes out of the rear of the rear brake mastercylinder. It'll have two wires connected to it.

I have a 1989 Heritage softail classic just rewired a new rear light and now my brake lights dont work neithe front or back but the running lights and signal lighst work fine

The light unit has to be grounded.When you rewired did you forget to reattach the ground wire?Turn the lights on and hit the brake,what does the tail light do? If it goes dim or off you have a bad ground.It worked before the new rear light,right?Check for compromised ground.

Left rear turn signal and brake light dont work

You have a broken wire to the turn/brake light portion of the light as they use the same wire. Or where the plug goes into the light assy could be bad. Torsion mount lights are horrible and you should think about replacing with a universal light that you can wire direct.
