What is the purpose of Type C lights?

The purpose of Type C lights is specifically to mark the roadway edge during nighttime hours. These lights are designed to enhance visibility, helping drivers understand the layout of the road and maintain safe navigation after dark. By marking the edges of the roadway, Type C lights play a critical role in preventing accidents and ensuring that vehicles stay within safe driving parameters. Their low-intensity illumination is crucial because it aids in guiding drivers without creating glare that might impair visibility. This function is particularly important in construction zones, work zones, or any area where the road's boundaries may be less defined.

Type C lights serve a unique role distinct from other types of lights designed for various signaling or warning purposes, showcasing their specific application in roadway safety management at night.
