I bought a Schwinn Breeze ladies bike at a thrift store that had the front and rear lights with the little generator that runs off the rear wheel to supply current... I took the bike apart to clean it up ( it 's still apart ) gotta get tires, they're a hard to find size. I got to thinking that the lights would work off the WHITE wire.... and so I installed them on my Schwinn Cruiser ... and GUESS WHAT?.... they light up perfect... I'll guess; that Schwinn Breeze is 40 or 50 years old...I am thouroughly impressed with my ingenuity.... LOL.... IT WORKS...!!!!!
