In the 1920's Neon lighting quickly became a popular fixture in outdoor advertising. Visible even in daylight, people would stop and stare at the first neon signs dubbed "liquid fire". Bailey Sign, Inc. is one of the only sign companies in Maine and throughout New England with the ability to produce custom neon glass in-house.

Georges Claude was the first person to apply an electrical discharge to a sealed tube of neon gas to create a lamp. Georges Claude displayed the first neon lamp to the public on December 11th 1910, in Paris. In 1923, Georges Claude and his French company Claude Neon, introduced neon gas signs to the United States, by selling to a Packard car dealership in Los Angeles. Earle C. Anthony purchased the two signs reading "Packard" for $24,000.

During the last decade LED lighting is being introduced more and more, artist, architects, and interior designers are beginning to discover its exciting possibilities as a more eco-friendly lighting solution, LED lights use about 1/10 the amount of energy used in traditional light bulbs. LED light bulbs last about 30 times longer than traditional light bulbs and are now used in everything from elegant dimmable LED lighting to LED waterproof lights for outdoor applications.
