I REALLY need some help.
So i have a 2012 Sportster 1200 CP.
The rear LED taillight stopped working. The brake light works fine.
Its just the taillight that doesnt work. All fuses are good to go.
Anyone have any ideas as to what is going on? I dont have the 400+ to give to the dealership to install a new one.
Thanks!

It's likely the LED modual (on the LED circuit board) that's bad. But, run it to ground by checking teh connectors under the seat. You have two that are identical that go to each of the TS, then a third slightly different connector that leads to the tail light.
Unplug it and re-plug it if you haven't already done so.
Next, if you have a meter, check for voltage on the red wire with yellow stripe.
The blue wire is the brake light and it obviously works.
The gorund is common to both brakes and tail light, so it obviously works.
If you get a voltage signal on the red/yellow wire, something is wrong with the tail light. If this is trhe case, check any connections inside the lamp, and the wires leading to the lamp.
If you get no voltage, the wiring/connector has an issue or the Body Control Modual has failed.

One thing though. I have no way of actually getting into the lamp like you suggested. it is all one solid sealed piece. even the wires going into the housing are sealed in .
Looking at the schematic, it looks like the tag light and tail light are the same circuit. You may be screwed.
Before buying new ($$$), look at aftermarket lamps from Custom Dynamics and other companies.

Sorry to hear this.
When I had similar problems, I found that one of the wires that runs along inside the rear fender had popped out of it's run, and was being gnawed by the tyre.
Snipped it, cleaned it, then re-soldered and it all works fine. Worth a look I guess!
Good luck, mate!
