I recently installed boom (windshield speakers) and a run/stop/turn module on my 2010 RKC. My problem is that my brake lights/turn signals stay on constantly. There is not even a flicker when I apply brakes. I removed the module and break light still stays on.I checked the acc. fuse per suggestions I received on forum last night and fuse is fine. However, after I removed the brake relay switch the brake light finally went down to running light brightness. Is it a problem with the brake light relay? What would have happened to it ?

 

I've got the same problem. I installed an HID headlamp and a few days and a couple of rides later, my brake light went out completely. No blown fuse or bulb when checked. I had the check engine light come on, I pulled the code and it translated as a "brake watch low" code. Now I have to figure out which one is bad and change it. I'll be watching this thread.
