97 ultra classic
Replaced rear tail lights with led's and everything went STUPID! They said the lights were plug and go,but that doesn't seem to be the case. When I fired it up the first time everything worked. Did some speaker changes and lost all the lights. Removed the Accy locked fuse while checking it out and lights came back. Now I have no turn signals and the bottom rear running light went out and the break light is stuck on. What in the sugar frosted flakes is going on, I'm lost.

Could you give a better description of the problem?
Exactly what lights did you replace?

Could the large magnet on the DB drive speakers be affecting the relays?
I still don't know why pulling the Accy Locked fuse would allow the lights to come back on.What is that circuit for?

You replaced the rear tail lights with led's.
I will take a guess that you have more than 1 tail light and you are not describing just the single factory fender tail light.
I will also take a guess that your factory regular 1157 bulb ( a (dual filament bulb) was replaced with an 1157 LED bulb that has two contacts at the bottom.
You state that "When I fired it up the first time everything worked"
Did some speaker changes and lost all the lights.
We can not see the bike so description needs to be clearer.
From a distance it reads like you may have been doing some other work on the bike.
The front hand brake lever has a switch with a rubber tip that works backwards (out is ON and in is OFF).
That switch on front hand brake lever is easily damaged if someone did not protect the rubber tip during hand switch control work.
The symptom would be a stuck ON brake light.
The wires that enter that switch control and the handgrip are also very easily shorted if someone was not careful and pinched the wires while closing the clam.
No mention of LED lights utilized but i will guess they are OK since that era of motorcycle does not have CanBus.
To clarify:
Based on limited information it reads like the rubber tip for hand brake switch was damaged and the wires pinched at hand control.

I don`t have a clue as to what this means, that is why I asked you for a better description of the problem.
Good luck.
