Want to tell the driver behind you to "knock it off" without raising your middle finger? Want to tell him you're chill, happy? Want to just communicate with the world, share your pain, while you're crawling along in traffic on your way to work? Now you can electronically with this high tech Driving LED Emoticon.

It's wireless and attaches easily to your rear window. It flashes 5 different messages: Smiling face, Frowning face, "Thanks," "Back Off" and "Idiot." It's hardly essential. But for that guy who's been on your bumper the whole trip who you really really want tell "f**k off," the emoticon may just offer the perfect alternative: Frown face, followed by "Back Off," followed by "Idiot." (We recommend flashing "Idiot" at least 5 to 10 times for maximum effectiveness and personal gratification.)
