The 'Warp Drive' consists of two 1 Watt cyan Luxeon Emitter LEDs that are mounted facing down in the main control module above the rear wheel of the bike. The idea is to illuminate the rear wheel and an area of the road around the rear of the bike to create a kind of neon effect without the cost, weight and complexity of neon. The Emitters are wired in series with the 6 Volt white LED headlight so they are using power that would otherwise have been wasted as heat in a dropping resistor.

The Emitters are mounted on separate electrically-isolated aluminum heat sinks as shown in the first photo. The other photos show the assembly mounted in the main module. The LEDs are protected by clear plastic windows. Turn signals are next...
