Twilight lights and headlights are two important components in motorized vehicles, especially cars. Both have different roles in maintaining driving safety, especially during low light conditions or at night. The following is a brief introduction to the two:
-
Main Lights (Headlights):
- Main lights are the lights used on cars to provide primary lighting on the road in front of the vehicle.
- Usually consists of a pair of lights located at the front of the vehicle, one on the left and one on the right.
- There are two main light usage mode: long distance light (high beam) and short distance light (low beam).
- Long distance light is used when you are on a quiet road and there are no vehicles approaching from the opposite direction.
- High beam lights are used when a vehicle is approaching from the opposite direction or when you are in a residential area to avoid disturbing other drivers.
-
Daytime Running Lights (DRL):
- Dusk lights are lights that are on while the vehicle is moving, regardless of the surrounding light conditions.
- The main purpose of twilight lights is to increase your vehicle’s visibility to other drivers, especially in low light conditions, such as when it’s bright or in hazy weather.
- Twilight lights are usually located at the front of the vehicle, close to the headlights or on the front of the bumper.
- They are not as bright as headlights and are not used to light the road. In turn, they help your vehicle be more visible to other drivers.
Proper use of twilight headlights and headlights is essential in maintaining safe driving. Always make sure to use your headlights wisely, switch between high beam and low beam according to traffic conditions, and ensure your dusk headlights are working properly to help reduce the risk of accidents in low light conditions.
