Lessons:
Always prime metal surfaces even if the paint says it can be sprayed directly without.
Outcome:
This was returned to a family member as a gift and they were very happy to see it all cleaned up and in working order.

Before Restoration
The traffic light had been sitting outside for many years after it was decommissioned, making the cleanup a challenge.
Hardware
The unit is powered via a wall plug and uses a step down voltage converter to power the Arduino, which was used to control the relays and the rotary encoder.
After Restoration
After the light was stripped of old paint and cleaned up it was prepped for new paint. New reflective light cones were also installed along with new wiring and bulb sockets.
