Bicycle Christmas lights -- drivetrain
I bought a small string of battery powered LED Christmas lights from Walgreens and mounted three sets of them to my Raleigh One Way bicycle.
When attaching these on the drive side of the rear triangle, ensure the lights and wires are out of the way of *all* moving parts, including shifters and shifter cables (if any), brakes and brake cables, chains, wheel/tire, crank and pedals. Many people also will hit the chainstay with their right shoe at least some of the time, so be sure the light won't get knocked into the wheel when you do that.
See the EXIF data for exposure information.
