DIY: Kilo-Lumen bike headlight

Sometimes lighting up the road ahead of you isn’t enough. Sometimes, you want to light up the entire neighborhood. If so, the Kilo-Lumen bike headlight is for you.

I started biking to work this summer and needed a good headlight and taillight. I didn’t want to spend a lot, but I wanted extreme visibility. For about $150 I ended up with a headlight that puts out somewhere around 1200 lumens, and a really effective tail light. The power source is an 18 volt Ryobi power tool battery which is both easily replacable, and quickly charged.
