Neonetics Neon Signs feature multi-colored, hand blown neon tubing. The Chevrolet C10 Sign has bright red and white neon tubes. The glass tubes are backed by a beautiful full-color image, and the entire sign is supported by a black finished metal grid. The sign can be hung against a wall or window; they can even sit on a shelf. The sign measures 23 inches wide by 25 inches high by 4 inches deep. Neonetics neon signs have a warm mesmerizing glow, and are powered by industrial strength transformers, which operate silently and more efficiently than incandescent bulbs. All you do is hang it up and plug it in ? no assembly or special wiring required. Fully licensed by General Motors through Neonetics Inc. For Indoor use only.
