What is the use of day lights
Daytime Running Light (DRL) is a traffic light installed on the front of the vehicle, which is mainly used to improve the visibility of the vehicle during daytime driving, thereby enhancing driving safety. The following are the main functions of daily running lights:
Improve vehicle recognition
The main function of day lights is to make it easier for other road users to spot your vehicle, especially in the early morning, late afternoon, backlight, fog or rain and snow conditions with poor visibility. It reduces the risk of collision by increasing the visibility of the vehicle.
Reduce traffic accidents
Studies have shown that the use of daytime running lights can significantly reduce the accident rate during daytime driving. For example, some statistics show that daily running lights can reduce about 12% of vehicle-to-vehicle collisions and reduce 26.4% of car crash deaths.
Energy saving and Environmental protection
Modern daily running lights mostly use LED lights, energy consumption is only 20%-30% of the low light, and longer life, both energy saving and environmental protection.
Automatic control and convenience
The daily running light is usually automatically lit when the vehicle starts, without manual operation and easy to use. When the low light or position light is turned on, the daily running light is automatically turned off to avoid repeated lighting.
Can not replace the lighting
It should be noted that the daily running light is not a lamp, its light divergence and no concentrating effect, can not effectively illuminate the road. Therefore, it is still necessary to use low light or headlights at night or when the light is low.
summary : The core value of daily running lights is to improve driving safety, rather than decoration or lighting. It is an important part of modern automobile safety design by improving vehicle visibility and reducing accident risk, while taking into account energy saving and convenience.
Daytime Running Light (DRL) is an important safety feature for vehicles to improve visibility during daytime driving. If the daily running lights fail, it may affect driving safety. The following are the common causes and solutions of daily running light failures:
The bulb is damaged
Reason : Bulbs age or burn out due to prolonged use, voltage fluctuations, or quality problems.
Solution : Check the lamp is not damaged, if found aging or burned, need to replace the vehicle specifications of a new lamp.
Line fault
cause : Aging, short circuit or poor contact of the line may cause the running light to fail to work normally.

Solution : Replace the entire daily strip or light source to ensure compatibility between the new and old parts.
Sum up
Daily running light failure can be caused by a variety of reasons, including lamp damage, wiring failure, switch problems, blown fuses, etc. It is recommended to start with the light bulb and fuse, and gradually check other components such as circuits and switches . Regular inspection of the vehicle's lighting system can effectively prevent the failure of daily running lights and ensure driving safety.
