The best way for advertising hands down! I am a remote control LED Message Board that is suction cup to any/ all vehicles, can be hung on a wall, and/ or sits an inch high on a flat top surface. 400 to 500 words can be programmed to scroll at a time. And most uniquely....I can be wrapped or painted to match your business logo, favorite team, your company logo, color of your car, or any design you want. Endless usage opportunities with a Tailsign!! Sharing/ Marketing and Advertising while driving! I promise that whatever you say on a tailsign...WILL be read! Sit back a watch the response. Amazing!
