If you have ever wondered what is inside of a traffic light and just how the system works, you are going to enjoy father and son team Dan and Lincoln Markham’s latest episode of What’s Inside.

zoom in


This time out, they got their hands on an actual stop light and then cut it open to find out what is inside. We also get to learn a bit about the computer system that runs the stop lights. It is actually really interesting. The lights themselves are not complicated, but the system that runs them all sure is. These days, traffic lights don’t just run on timers, but actually detect traffic and adjust their timing accordingly.

On a side note, how many people can convince their city to let them do this?
