Kilo-Lumen bike headlight

Step 11: Taillight

Possibly the most important light on a bike, most taillights are woefully inadequate. 18 Superflux/Pirhana LEDs work well, and if you have a rack on the back of your bike, its a convenient place to mount it.

This build is really easy. Find a surplus metal housing, gut it, cut out a plastic cover, and glue in the strips of LEDs. Of course first you have to find strips of LEDs, or make a PCB etc. In any case, its a box with LEDs, a Taskled CC1W current driver and thats it. People haev told me I look like I'm on fire. Its as bright as the LED brake light of many cars, and its wide dimension distinguishes itself from the majority of bike taillights. I also have this running off the 18 volt Ryobi battery.
