I have my Supernova E3 triple dyno light set up so that I can quickly disconnect it and take it with me if I have to park for long. It also alows me to easily switch the light between bikes. Supernova makes these really nice gold connectors you can use to facilitate the quick release and the handle bar mount also has a quick release for the lamp.
