SOURCE: V-Rod 2003 rear breaks does not work properly

Check the level of the brake fluid in the master cylinder for the rear brakes. Then, try bleeding the brakes.

To bleed the brakes, open the bleeder valve on the rear brake caliper about a half turn. Press the rear brake slowly until it stops and hold it there. Tighten the rear brake bleeder valve while holding the rear brake pedal down. Then, release the brake pedal. Wait a few seconds and try the brake again. If it doesn't feel any better, go through the procedure several more times. Make sure you do not allow the rear master cylinder to run out of brake fluid. Check the master cylinder top cover or your owner's manual to find out exactly what type of brake fluid goes in the master cylinder. Do not mix different types of brake fluids. Dot4 and Dot5 (U.S.) brake fluid will not mix and will cause you severe problems. If this doesn't work, a complete overhaul of the rear brake system is called for.

SOURCE: My rear tail light does not work when the front

You should have two filaments in the reat taillight lamp, one for tail light and one for brake light. You are not confusing these filaments/functions are you?

What you seem to be saying to me is that you have a lamp that had no tail light filament (burned out) but does have a brake light filament still intact.

Remove the light and check it visually and/or with a contunity tester.

I hope this helps you ...

If I misunderstood your question, please ask me again

SOURCE: Brake lights,turn signal and horn not working...

Check the wiring within the headlight shell--look for connectors that may be corroded or pulled loose. A little WD-40 will favor connection integrity when sprayed into the connectors, then coupling and uncoupling them several times. Hope this helps!

Last year I put LED lights/signals on my 2010 Ultra. Last week the left rear turn/running light stopped working completely. Any ideas what may be wrong? I looked at the connections into the rear brake...

Check for power at the light connector, if there is none go back up the line and check at the next connector etc if there is power at a connector then there is an open between that connector and the last one that had no power. If there is power to the light assembly itself then the assembly must be defective but you could bring known power and ground directly to it on the bike or on the bench, obviously if it works then the light assembly is good and if it does not work then the light assembly is defective.

Rear turn signal lights are not working, Tail light and rear fender light work but not the turn lights

Do both sides not work??? What are you calling the tail light and the rear fender light??? Is the brake light working??? What if anything was done on the bike prior to this.

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.

The blinkers work but the brake lights dont for a 2003 harley davidson dyna super glide...how can i fix this?

Check to see if the brake light works when you apply the front brakes. If they work but if the brake light won't come on when the rear brake pedal is depressed, the rear brake light switch is bad. Find the rear brake master cylinder and you'll see a metal line coming out of it. Follow the line back towards the rear of the bike until you come to a tee in the line. The brake light switch is screwed into the tee and a couple of wires plugged onto it.

If neither your rear brake light nor you tail light works, first check the bulb. If the bulb is good, you might have a wiring problem. The wiring is a sub-harness that plugs up under the seat area and then runs back to the rear light assembly. The turn signal wiring usually run down each side of the rear fender behind the fender struts.
