Neonetics Neon Signs feature multi-colored, hand blown neon tubing. The NHRA oval in can neon sign has red, white and blue neon tubes, and measures 30 inches wide by 15 inches tall by 6 inches deep. The glass tubes are backed by a beautiful full-color image, and the entire sign is housed in a white-finished steel can. The sign can be hung against a wall or window; they can even sit on a shelf. 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 National Hot Rod Association through Neonetics Inc. For Indoor use only.
