Headlight and Reverse Lights monitor for YouTube Commenters - UNTESTED but should work fine.

#!/usr/bin/python
# A quick hack of my button monitor script to monitor headlights and reverse lights to
# Dim the screen and switch to the reverse camera.
# I have not tested this...
# Remember, the switch or opto is switching to ground, so the logic is inverted... 0 = on 1 = off
# Also, you would run only one of these "Monitor" scripts. you can't be running RearviewMonitor.py AND LightMonitor.py
