Picture of Five Dollar Bike Light
If you have ever looked at bike lights you already know, they are expensive! I found myself in need of a light, and unwilling to pay a high price. So I did what I often do, I stopped at the hardware store and got to work!

As with all of my projects, I made it at TechShop! (http://www.TechShop.ws)

Step 1: Gather Materials

For the $5 Bike light you need:

2 3-1/2 inch LED Flashlights
2 3/4 inch PVC Slip T-Fittings
2 #2 Pipe Hangers
1 piece of 3/4 PVC (about an inch)
1 1/2 inch long 1/4-20 bolt and nut.




Paint (I used Truck Bed Coating)

Cars come with two headlights so why can't bike lights be sold as a double.This is a simple and cheap solution to the question.As a comparison , I looked on ebay and they cost around $25-$30 + postage depending on where you live.These materials , I already had and then bought two torches that have a flashing red beacon on the end for $2 each.The result , twin headlights + twin warning lights all in one housing that can be reveresed and used either on front or back of bike.

This was a great project. I really light up the streets with this set up!

These are really nice.

I probably would have put red lights on the back, but that's just me. The way everything mates up, it looks like it was designed that way, which is really cool. Nice work!

nice solution!! I love PVC and LED projects.
