Comparison between LED and halogen

I'm just gonna run that bulb and see what it does. If its not bright enough to see by, I'll figure something else out.

It will be very dim at 7.2 volts. Bulbs get exponentially brighter with increased voltage. Use 2 batteries in series or get a $15 12 volt spa battery off eBay. I am running a 55w halogen headlight and 10w tail light from a 4.5ah battery I got for $15 including shipping and they last a good 40 minutes per charge.

He's running it at 14.4 volts, it should be bright.
