Last year, dissatisfied with the low quality of commercially available bike wheel lights, I set out to make my own.

Several kilograms of filament and several meters of LED strips later, I had a solution that worked. Bright, eye catching wheel lights that I only had to charge once a week.

I toyed with the idea of starting a small business to sell them online, but there were too many unknowns.

So I released them open source: https://www.instructables.com/DIY-3D-Printed-Rechargeable-Bike-Wheel-Lights/

Ride brightly, my friends.
