do have brake light on my 05 Deluxe. I have a Custom Dynamic LED board and one of my buddies noticed i didn't have a running light but i did have a brake light. I took it off and called Custom Dynamics for a replacement but in going through the steps with them to see if it was the full board or a part of it they had me to put back in the 1157 bulb and same thing i have no running light but do have brake light. So any ideas as where to start to find the problem? I did put on the Truck lights (headlight and passing lights) other than that nothing has been done to the electrical.

Any help is appreciated.

 

So you don't have a tail light with the led, or your stock light?
Do you have a volt meter or test light?
Sounds like the wire is bad under the fender.

 

i don't have running light with either LED or 1157 bulb. My buddy is bringing a test light and i too think under the fender is suspect.

 

Do the front running lights work?

 

Yes, everything headlight, passing lights, turn signals works but the running (tail) light doesn't.
