Neon sign. The neon sign is an evolution of the earlier Geissler tube, [11] which is a sealed glass tube containing a "rarefied" gas (the gas pressure in the tube is well below atmospheric pressure). When a voltage is applied to electrodes inserted through the glass, an electrical glow discharge results.
In 2012, MONA turned down the donation of the neon sign of an Arby's restaurant in Santa Monica, California due its size, reportedly 20 feet wide by 35 feet tall.

Signs frequently use lighting as a means of conveying their information or as a way to increase visibility. Neon signs, introduced in 1910 at the Paris Motor Show, are produced by the craft of bending glass tubing into shapes. A worker skilled in this craft is known as a glass bender, neon or tube bender.
An iron cored neon-sign transformer, with a 9-volt battery for scale. A neon-sign transformer (NST) is a transformer made for the purpose of powering a neon sign. They convert mains voltage in the range 120-347 V up to high voltages, in the range of 2 to 15 kV. These transformers supply between 18-30 mA; 60 mA on special order. [1]
