Daytime running lights (DRL) refer to a type of front lighting system in vehicles that are automatically activated during daytime hours to enhance visibility and increase safety on the road. These lights typically consist of a pair of white or amber headlights, fog lights, or LED strips that remain continuously illuminated when the vehicle is in motion, even in well-lit environments.
The purpose of daytime running lights is to ensure the automobile is easily noticeable to other road users during daylight hours, reducing the likelihood of accidents. They help overcome reduced visibility conditions, such as glare, shadows, or unfavorable weather, by making the vehicle more conspicuous. By increasing the awareness of pedestrians and other drivers, DRLs help prevent collisions and improve overall road safety.
Daytime running lights are distinct from regular headlights as they are designed to be less intense and provide less illumination. They operate at lower brightness levels to prevent blinding or dazzling other road users. DRLs are typically wired to the ignition system, automatically switching on when the engine starts, and shutting off when the vehicle is turned off.
These lights have become a mandatory safety feature in many countries or regions, including some European Union countries, Canada, and certain states in the United States. However, regulations may vary, with variations regarding color, placement, and permissible lighting technology. Manufacturers often integrate DRL systems into new vehicles, but retrofit kits are also available for older models wishing to benefit from enhanced visibility during the daytime.
