I have had the same prob. with my 07 FLSTC I had changed my grips out and every thing was good until the brake light would not stay off I noticed if I just pressed a little on the brake lever. There is a little micro switch behind the hand lever and there is a tab that touches it when the brake is pressed and it goes off when you release it. XEA says that you can try bending the tab if you are brave butt be carefull because it is cast aluminum I recomend taking the your bike to your local bike shop. I have had nothing butt heck out of mine since I cahnged my grips out. I took mine to the harley shop it aint cheap. and good luck.
