we used a cheap 3W led flashlight that normally used 3 aaa batteries for power. We had it hooked directly to the 5v output on the digital sidecar with a couple resisters to limit current draw. We had it shine through a 6 inch piece of pvc pipe to limit its effect on the opponent drivers and we only lit it up when we were about to shoot. Worked pretty well from < 20 ft.
