This is how to make a bike light out of all recycled parts. Most of which come from an old broken flashlight and other miscellaneous scraps. I would appreciate comments on how to improve it and rating it is greatly appreciated.

Step 1: The Materials

- A broken flashlight - used to get the lightbulb/fixture and lens
- wire
- switch - any on/off switch works - i used the toggle switch for looks
- 9v battery and connecter
- 5v regulator
- broken reflectors - for handle bar attachments (anything that clamps on can be used for this)
- container or box - again, i used a recycled candy container

Step 2: Wiring Up the Light

The wiring is fairly simple. Just follow the schematic. This is what i used since my light ran on 6v. If this does not work for the light you have, this website will help you figure out the resistance needed using a resistor. I am sorry for the lack of pictures, i had trouble using the camera and iron at the same time.

Step 3: Preparing the Case

I used a hot glue gun to attach the first handle bar mount to the light lens hood. For the attachment on the case, i drilled holes for the bolts. A hole was drilled at the bottom of the case for the switch, and a hole was drilled in the top of the cap for the wires to run through.

Step 4: Putting It All Together

Now just attach the switch in place, run the wires through the hole in the top (for me this required unsoldering from the fixture), plug in the battery and test out your new recycled light.
