If you read above from 2015 I had a bulb in a traffic light that would not light. I had only noticed this after everything was installed. After some thought, I did not want to tear it all apart, so I just left it as is and thought traffic lights burn out in the prototype too.
Four and a half years later, I decided to redo my road. It was originally foam board but over time it started to warp, so I ripped it all out in favor of masonite.
During the teardown I remembered the traffic light would not light. So I took it apart and found it was just a bad solder joint on the wire to the yellow light.
All is well. Pics below to show how the light was disassembled.
First, use a hobby knife to break the seal and get some separation.
One you get a little separation between the two halves, then a common screwdriver can be use to finish removal.
The two halves are removed and you have total access to lights and wires.
Press fit the halves back together and test the lights. I used a 9v battery.
Notice the jaws of my helping hands scratched the pole. I will weather these, so I'm not worried about it. But if you like yours shiny and new, be careful and use something like a cloth to put in the jaws of the helping hand.
Have Fun!
