Light is what causes light pollution. Neon by itself won't do a thing unless used in a lit neon sign.
Neon is a light non-metal, a noble gas.
It contains neon gas as it is also given in its name "neon light". However, it does contain other gases too but in negligible amounts.
An electric current passes through the neon gas inside a neon light, ionizing the gas and causing it to emit light. This process excites the neon atoms, causing them to release photons and produce the characteristic colored glow of the neon light.
The gas that emits a bright reddish-orange light is typically neon. Neon gas is commonly used in neon signs and lighting due to its distinctive color when ionized.

Neon gas emits red light when electricity flows through it. This phenomenon is used in neon signs and neon lighting.
Its mostly Argon and a small amount of mercury. Its the main ingredients inside a flourescent lightbulb, which are used to light up billboards and highway signs. See the related link for more information on flourescent bulbs.

neon is a natural substance that is modified by man to glow. Neon is an "inert" gas which does not form any compounds. It is tenth in the periodic table. Neon means "new". It is used (at low pressure) in gas discharge lamps where an electric current through the gas causes it to glow red.
Neon is a gas. It does not contain anything as it is an element.
Neon (Ne) is a chemical element.
