IF you search the web, you can find good instruction on DIY LED moonlighting. I used 6 2600 mcd LEDs with 30 degrees iof output. I paid about 4.50 US each at radio shack + resistors and a potentiometer to regulate the light output. Lastly you use an old cell phone charger or some other 5 - 9 volt source of power. Conect everything with speaker wire, solder connections, and wrap with eltrical tape. Total cost for me was ~ $40 + 1.5 hour labor
