ummm i'm not sure how he did it. if he had a drill, screwdriver or any weapons around my bike i wasn't aware of it and my brain sets off alarms when he brings those things around my bike.
he might have something on his website (
www.gascapitalcustoms.com) of what he did, but your best bet is just to message him and he can tell you what he did. i am pretty sure he just switch the plastic thingy from behind the lights out with what was in my fairing...let me know if he did have any weapons around my bike
just checked the facebook page and he had a little bit of info. on the adapter for the older bikes using the newer style of lights
