Some assembly required, batteries not included
December 13, 2008
A dynamo-or-battery-driven set of lights for a bike — 200 lumens white to the front, amber low beams and running light, and a red-orange tail-light. It’s about a 3-watt system, using mostly-latest LEDs from CREE (white) and Luxeon (amber and red-orange).Parts, not including spare tape, solder, hardware, etc.
Low beams. Notice the sharp cutoff. This was taken with a flash.
High beams. Some cutoff, but not as much.
The little blue box. The rectifier is below, the regulator and plugs for rear and running light, are above.
