I had the same idea when I installed my led headlights too. My idea was some red led strips (to match the red stripes) which would go under the tank??...seat?...I dunno. My cobber had a silver bigdog chopper and had blue lights under that. When he had a BBQ, the bike was out on display with the blue lights going...music pumping...good company and food. So I thought...hmmmm, the Rocket would look good with lights alongside his "Indian Chieftan" at his BBQ! I'm sure he has added lights to that too!
So far, just an idea.....
