Say exactly what you’re thinking to other drivers when you have the CarWink Car Communication Device. Attaching to the back windshield of your vehicle, this electronic device can display a variety of messages to your fellow drivers. Of course, it can handle tons of cute messages such as emoji. However, it can also relay important information such as “pedestrian crossing” and “accident ahead.” This technology is revolutionary in that it allows you to communicate like never before. All of this is possible without requiring other vehicles to have the technology. The bright LED lights work perfectly at night as well as during a bright day. Finally, the CarWink has a range of 30 feet so you can notify more than just the driver behind you.
