I haven't mounted the lights yet. I 'm messing around with a square piece of aluminum. Thinking about drilling a 1" hole through the center,slicing just off center then pinning to bars via set screws. This would give me a small clean block to polish up right between the risers. Drill that puppy for four tiny electronics leds and I picture a real cool sleek set-up. Or,I just noticed a real cool bar mounted set in JP cycles to do exactly what I need.
