I found that it was so cold in Winnipeg that my bike lights could not withstand the chill. the plastic lenses would crack, and there is certainly no bike lights with batteries that will last when exposed to the -30c for an hour.
I’ll bite on that. Plenty of cold and snow to test with here.
Large metal throw switch that will never crack off or become disconnected from a SMD soldered board… Looking at you Fenix lights!
The reflective lens is 3d Printed with eRyone red TPU. I designed the shape to act as a reflector/diffuser and this gives the light it’s distinct look. The bulbus shape give more surface area to project the light.
The Battery case for the Li Ion 18650 cells is 3D printed with PLA that will change colors at 50-60c. This allows for a visual should you ever be overcharging your pack or running the batts too hot. The battery pack is meant to be remote in a backpack or pocket to maintain the heart.
The 12v LED bar puts out plenty of Lumens and easily competes with vehicle lamps.
After two winter seasons of daily fatbike commuting I can say that the only thing that broke was the small wire connecting to the LED board in the light fixture. I added hot glue as strain relief for the future. There is a lot of salt on the roads that make it similar to living by the ocean as far as things corroding.
Version two to have complete caps and integrated battery. Ideally an Arduino Nano as control circuit for some cool effects and battery management. The slots for the mounting straps have been beefed up.
Stay seen out there!
