# Reflector (Catadioptric)
A reflector is a road safety device that reflects light coming from external sources, such as the headlights of other vehicles. It is installed on vehicles to increase their visibility during the night or low light conditions, allowing other drivers to detect their presence from a greater distance. They are especially important on the rear of vehicles and on traffic signs.
