If you ever speed through green lights that suddenly turn red, you might want to know about a device mounted to your car's console that could prevent that from happening. It also comes in handy when you're sneaking in some work at a red light, only to have the guy behind you honk when it turns green.
There's an app called EnLighten for iOS and Android phones that alerts you when a traffic light is about to change. When you're driving, it shows you the color of the traffic light ahead of you, then lets you know with lights, sounds and a countdown clock if you'll make it through at your current speed.
EnLighten predicts these changes in part by tapping into a city's smart traffic signals. It also takes cues from your car's GPS about your location and speed.
Now, the EnLighten iOS app just got easier to use. If you drive a BMW, that is.
