Traffic light.

Traffic lights are useful to coordinate traffic at intersections. Traffic lights can be used at three or four way intersections. Hardware wise, Traffic lights are Duckiebots without wheels, and a beautiful different chassis.

Reminder: for traffic lights to be recognized by Duckiebots, appropriate signage must be placed at intersections (traffic light traffic sign instead of stop sign).

This section describes the physical assembly and installation of traffic lights.
