If you want to modify LED light strings - this may be a good source to start http://www.geeks.com/details.asp?invtid=A-USBLEDB-1 these run on your computer's USB port [ 5 volt] -
I think if you look up the web pages people have regarding using LEDs in the vanagon dash lights - the same resistor and be added in line to these to bring the voltage down.
