This page describes the construction of a bike light comprising three 3W Luxeon LEDs. This project had three main goals. 1.) Make a light suitable for use in 24-hour mountain bike racing. 2.) Use readily available material as much as possible. 3.) Offer the details to the community and invite any and all comments.
