Final answer:
Daytime running lights (DRLs) are a safety feature on vehicles that are designed to improve visibility during the day. They make vehicles more visible to other drivers, reducing the risk of accidents.
Step-by-step explanation:
Daytime running lights (DRLs) are a safety feature on vehicles that are designed to improve visibility during the day. They are typically bright white or amber lights that automatically turn on when the engine is running, and they remain on even when the headlights are not in use. The purpose of DRLs is to make vehicles more visible to other drivers, reducing the risk of accidents.
By having DRLs on during the day, it increases the chances of other drivers noticing your vehicle, especially in low-light and poor weather conditions. DRLs are not as bright as headlights, but they still serve the purpose of making your vehicle more visible from a distance.
For example, if you observe a vehicle with DRLs, you will see that the front lights are on, even in daylight. This helps distinguish the vehicle from the background and alerts other drivers to its presence.
