Daytime running lights (DRLs) are automotive lighting devices that automatically turn on when the vehicle is running. They are typically brighter than parking lights and improve a vehicle's visibility during daylight hours, enhancing safety for both the driver and other motorists on the road. DRLs come in various styles and can use LED or halogen bulbs. When considering DRLs for your vehicle, factors to consider include brightness, beam pattern, and ease of installation.
