Why is front bike lights green?
Most bike front lights are white. When LED (light emitting diode, which offers much better battery life in a much smaller package) lights were first introduced, white LEDs were not available and so green ones were used instead. These were intended only as "supplementary" lights because, at the time, using LED lights in place of those with conventional bulbs was illegal in the UK. This law has since been changed due to modern LEDs being easily bright enough to use them alone, but the law still demands that a white light is used at the front of the bike - although green LEDs are still found in some cheap bike lights, they're still illegal unless used with a white light (either LED or conventional bulb). Lights with white LEDs can now be bought for just a few pounds, about the same as those with green LEDs, so there's really no need to continue using them and risking a fine should the police stop you.
