#7: A Visual Traffic Light Countdown
This traffic light has a nifty countdown timer, which lets drivers know how long they have before a signal goes from red to green to yellow. This is a simple yet effective way to encourage safe driving, and we love it! With these simple countdown timers, there’s no need to anxiously tap your fingers on the steering wheel, wondering when that pesky red light will turn green.

Also, a countdown timer like this eliminates the guesswork when it comes to driving through a yellow light. A lot of drivers like to take a chance and speed through a yellow light, creating potentially dangerous situations. With this timer, drivers know how long they have to make it through an intersection. Now that we think about it, why weren’t traffic lights designed like this in the first place?
