Caption: Neon lights. Neon lights of various colours on a building. A neon lamp consists of a glass tube containing neon gas at a low pressure and two metal electrodes at either end. When an voltage is applied, the gas becomes ionised and begins to glow as it transmits a current between the electrodes. Pure neon has a red-orange glow. Different colours can be achieved by the addition of impurities such as argon or krypton. Neon lights are more efficient than carbon filament lamps. Photograph of the Neon Theatre Marquee, America.
