Daytime Running Lights (DRLs) are lighting systems on vehicles designed to increase visibility during daylight hours. They automatically turn on when the vehicle is in operation, helping to make the vehicle more noticeable to other drivers and pedestrians. DRLs typically use lower-intensity lights, such as LEDs, to conserve energy while still enhancing safety. The primary purpose of DRLs is to reduce the risk of accidents by improving a vehicle's visibility in various lighting conditions. Many countries have regulations that require new vehicles to be equipped with DRLs, reflecting their importance in road safety.
