My Traffic Light is an Android application developed by Tri-Angel Software and Games. It is a free educational app that teaches you how traffic lights operate. With this app, you can control the order of signal changes via preset cycles and change the signal light cover patterns by choosing one of three lenses (a blank lens, a striped lens, or an LED lens).

The app offers an automated timer, but you can also turn it off and control when the signal changes manually. Overall, this app is an excellent way to learn about traffic signals and how they work. It is easy to use and provides an interactive experience that makes learning fun.
