So Mexico Wanderer, you should have some rudimentary ideas now on how to go about designing the juice side of those LED's you've been playing with. You might have to hunt and peck to find a driver that will supply the milleamps or amps you need to drive 3 of those bulbs in series, at 10 watts each. Any way you slice it, though, unless you have some serious heat sinking capability, you'll have short lives and heat management issues with those 10 watters. When mountain biking, I've been adamant about having to keep moving and air flow over my night lights. Turn them off if you stop and cease forward motion.
