This is a little project for a bicycle electric with LED Lights. The used lamp is an AXA Luxx70 which has its optimal operation point at 7.0V. Below 7.0V the lamp lights in
"steady-light" mode at 50mA, at 7.0V with full light (high beam) at 300mA, above 7.0V the current consumption increases fast, but the LED light intensity does not.

This schematic covers additional features: 12V - eg.for a NiMh accumulator and 5V to connect USB gadgets - eg. a Garmin GPS device, or my mobile phone.
