Well guys I said a while back I was working on a project and I came up with an answer.
I took an old LG cell phone and I used that as a power source for my lights. I connected a wire to the brass fingers that touch the battery (cut the backing so the wires could stick out) ran that to the RCA plug so I can disconnect it at night to charge the phone, I then ran wire to the + & - terminals on my Schwinn lights both front and back. Switches work like normal and the lights are plenty bright enough. The battery is about 5 years old so it doesn't stay lit for more than two hours but I am working on a homemade LED headlight I found on the web. Soon I'll get the cast off then I can put them to use on the bike.
I have posted some pics. If you have any questions let me know.
Sorry about the crappy pics they came from my other LG cell.
Hope it Helps. I am also a proud member of the 20 MPH. club
