A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited.
