  • Taillight on fender.  The LEDs are all near the top because there is less space inside the reflector body near the bottom.
  • Here I popped out the reflector to show how things are wired.
  • A better view of the wiring.  Someday I'll cover this all in epoxy to protect it from vibrations.
  • A 3/4 view showing it all put back together again.
  • My messy basement with the bicycle lights turned off.
  • My first attempt at showing the bicycle lighting.  Half of the basement lights were on, giving ambient light similar to a late afternoon.  It's bright, but I look goofy spinning the wheel.
  • Second attempt.  The lights are off so you only see light from the taillight.
  • Third attempt.  Both taillights are on and you can see how much brighter the homemade light is than the commercial one.
  • Forth attempt with a bit of a closeup.  Writing these comments makes me realize that I should try another shot from the side showing everything that the LED taillight is lighting up.
  • Light output from the homemade light at a normal urban riding speed.
  • Light output from a Vistalite Nebula (non-blinking mode)

    The reflector is a Cateye fender mount reflector. They aren't available in the US new anymore, but you can find them on commuter type bikes from the 70s.

    The LEDs came from allelectronics.com.
