The tail light is based around SMD LEDs, mounted in acrylic to diffuse the light. The construction is beautiful, using custom PCBs and carefully machined acrylic to match the lines of the bike.

As far as warning lights go, a brighter light will be more obvious in the day time, but could actually hinder visibility at night by blinding other …read more http://pje.fyi/P716zQ
