This license plate frame has a programmable scrolling LED screen so you can communicate to fellow drivers.
Implications - Whether you want to tell the person behind you to stop tail-gating you, or spread the number of your business, the License Plate Billboard has you covered. It has the capacity to store up to 4 short messages or one long message up to 120 characters so you can almost say as you can in a Tweet.
With 147 LED lights sharing your message, there is no way that other motorists will be able to miss it. Customizable license plates don't have anything on the License Plate Billboard. Hopefully people don't get too distracted by the awesomeness of it.
