What type of light is used to mark the roadway edge during nighttime?

The type of light used to mark the roadway edge during nighttime is referred to as Type C. This classification is designated specifically for lights that create a clear and visible boundary on the road, enhancing safety for both drivers and pedestrians during low-visibility conditions. Type C lights are typically brighter and have specific characteristics designed to be easily seen in the dark, ensuring that vehicles can safely navigate along the edges of the roadway.

The differentiation between types A, B, C, and D signifies variations in brightness, color, and intended use, with Type C being the one recognized for marking edges of roadways, which is crucial for safety purposes. These specifications play a critical role in traffic management and reduce the likelihood of accidents occurring due to unclear pathways at night.
