Im going to show you how you can easily mount a small, handheld flashlight (such as Maglites) to your bike's handlebars, for basically free. I got the idea after seeing a cool hunting bike in a magazine and wanted to make it, and I might post an instructable on that too. You just need a few household items. Note: This may not work with all reflector mounts.
Step 1: What You Need
Here's what you need:
Front bike reflector mount
Duct tape, wire, string, something to hold flashlight in place
A philips screwdriver
