Does anyone know of a back light that turns off after 5 minutes of no movement? I'm tired of backlight being out of juice just because I forgot to turn it off ... I'm tempted to make a circuit and maybe even the sensor myself but I don't have the time for it and it probably already exists.

  The Ravemen CL200 does. And it's cheap. Doing a 2000km ride with it currently.
