Traditionally used for colourful signs highly visible at night, neon lights also find use as "underglow" car lighting. Available in different colours, these kits often include accessories necessary for installation.
Though called "neon", some kits actually use LED lights. While the gas tubes offer a uniform glow in every direction, LED models offer more colour options and durability. Equipping a car with neon lights adds an eye-catching glow that makes the car appear to float in a pool of light.
