I was in need of a couple of Red flashlights and I came across the following web page. I spent $12 dollars buying a set of three flashlights at Wal-Mart and some LEDs and Resistors at Radio Shack. I was an easy project. This was only the second time I have ever Soldered anything. I made a Red and a Green and plan to buy a couple more flashlights so that each of my kids will have one. http://www.dma.org/~wagner/led.htm Thanks. David Dunn 801-961-3253
