Neon lamp(Redirected from Neon signs)
A neon lamp is a light bulb that can make many colors when Noble gasses are inside of the bulb. For example, helium would give a light yellow color and neon would make a red or orange color when an electric current is run in the tube. It is normally used to make letters for signs. Different gases make different colors. Neon Lamps are used to make neon signs.
