In college, I designed a traffic light system for the Bob Bondurant School of High Performance Driving that controlled their accident avoidance system. These boxes replaced their existing system which used relays which were a constant source of failure, especially with the rough handling out on the track.
The photos below show the Accident Avoidance Setup in use.
