Underglow

Underglow refers to aftermarket lighting installed on a vehicle to illuminate the ground beneath it. Typically employing LED or neon tubes, underglow kits are affixed to the chassis or underbody of cars, trucks, and motorcycles. The primary purpose of underglow is cosmetic, intended to enhance the vehicle's appearance and create a unique visual effect.

Legality of underglow varies significantly by jurisdiction. Some regions permit certain colors or intensities of underglow, while others strictly prohibit its use on public roads. Regulations often address factors such as color (to prevent confusion with emergency vehicles), brightness (to avoid distracting other drivers), and visibility of the light source itself.

Installation of underglow can range from simple, plug-and-play kits to more complex setups requiring professional installation. Wiring, mounting, and securing the light tubes are crucial aspects of the installation process.

While primarily an aesthetic modification, some proponents argue that underglow can marginally increase a vehicle's visibility at night, potentially enhancing safety. However, this benefit is often outweighed by the potential for distraction and the risk of violating local traffic laws. The use of underglow is often associated with car modification culture and personalization.
