What is the purpose of a daytime running light (DRL) system?

The purpose of a Daytime Running Light (DRL) system is to increase the visibility of a vehicle to other drivers and pedestrians during daylight hours. DRLs are automatically activated when the vehicle is running, making it easier for others to see the vehicle, especially in conditions where visibility is reduced, such as during dawn, dusk, or overcast weather. By increasing vehicle visibility, DRLs help to reduce the risk of accidents, particularly in situations where it may be difficult to spot an approaching vehicle. DRL systems typically use the vehicle's headlights, turn signal lights, or dedicated DRL lights, and they operate at a reduced intensity compared to headlights used at night. The increased visibility provided by DRLs enhances overall road safety.
