I live and work in the suburbs west of Portland, Oregon. All my routes to bike to work are along major aterial roads, "protected" from the hundreds of cars, trucks, and SUVs by a thin stripe of paint.

Despite the risks, when I got an e-bike, I rode more that year than the rest of my life combined. As the days grew shorter and I started leaving work as the sun was setting, I started to worry for my safety. The lights on my bike didn't hold a candle to the overpowered headlights on modern cars, and reflective materials only work when you're already in the car's headlights - which might be too late.

Despite searching far and wide, I couldn't find anything that was designed for a daily commute. Most of the wheel lights I saw felt like they were meant for kids riding around the neighborhood, or group rides where you had safety in numbers.

So I made my own.

After months of work, and several spools of 3D printer filament, I finished a set of wheel lights that shout into the night, "look, a bike!" And I know that they work - several drivers have commented on them. I've had these lights on my bike for over a year now, day and night, rain and shine. Despite several thousand miles in the saddle, weeks of hundred degree weather, months of endless rain, and one bone breaking crash*, the lights are still on my bike,and still as bright as the day I first plugged them in.

These lights are too good not to share, and I released the plans open source. But, not everyone has a 3D printer or a soldering iron, so, I'm manufacturing small batches of them in my garage and selling them online.
