Thats what I did as well. I used a standard wet location aluminum outlet box to house a 15X30 lens and holder and a 10 degree narrow lens and holder with SSC P4 U-BIN Z-power LED's. I'm driving them with a dynamo so no batteries are required or current regulating driver circuits. The circuit I use is just 4 1N5818 diodes as a bridge rectifier and 1,000mF capacitor to stop flashing at very low speed, IE: walking the bike up steep hills.
