21led spot light for $4
I converted a Harley fog lamp to led using a 12 volt, 4 watt LED. That's roughly like 30-35 watts of incandescent. The beam is not focused down the road so it's not good for night riding at any speed but it's certainly visible even in bright sunlight and that was my goal...to be seen. I don't ride at night
so it works well for me. My turn signals, tail light, and brakelight are all LED as well. All the light's use very little current so battery life is excellent.
