So I have a problem. Yesterday I switched my old LED light to Radiantz (I have long fender and one laydown combined stop/running light)
So yesterday everything was fine, but today I noticed running light doesn't work (when breaking it lights up)
I'm away from home and can't look at my service manual. Is there a fuse for running lights? If yes - which one is it? 2011 FXDB

 

the accy 15a fuse controls the rear tail lamp parking side of bulb, and the light 15a controls the two rear side markers. the accy fuse circuit is also the 12 volt feed to the stop lamp switch so if your brake light works. check the tail light side of connector for any damage or backed out terminals if ok light is faulty.

 

Same fuse, faulty light.

 

or spend $5 bucks on a test light

 

Thanks guys. Looks like faulty light. Brake light is out too.. it's good that my rear blinkers work as stop, but bad news overall.. Need to ride back to LA in morning traffic tomorrow

 

Well, things are getting interesting. Put old taillight back - and it's not working.. Fuses seem to be ok.. What can be wrong?

 

Maybe pinched a wire while install

 

Checked all wires, tried old light one more time- and it works!
Checked new one just in case - busted.
