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:
Improved 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.
The daily running light may not be lit by a variety of reasons, the following are common troubleshooting and maintenance steps:
Check the bulb
Bulb damage is the most common cause of day running lights not working. Check whether the bulb is aged or burned out, and if a problem is found, replace it with a new bulb that meets the vehicle's specifications.
For LED daily running lights, it is also necessary to check whether the driver is faulty and replace the driver if necessary.
Check the fuse
A blown fuse may cause the running light to go off. Consult the vehicle manual to locate the fuse and check its status. If the fuse is blown, replace the fuse with the same specification, and ensure that the vehicle is operated in the state of shutdown.
Check the circuit
A line fault may cause current transmission to fail. Check the wiring harness between the headlight control module and the daily running light to see if it is damaged, aged or in poor contact, and repair or replace the wiring if necessary.
For the guide ring driver, check whether the connector is loose or improperly connected, and reinsert or replace it.
Check the switch
The day running light switch is damaged or poor contact may also cause the light not to turn on. Check whether the switch is working properly and replace or repair it if necessary.
Check vehicle Settings
The day light function of some vehicles may be turned off. Check vehicle Settings to make sure the daily running light function is turned on.
Check the headlight control module
If the headlight control module is faulty, the daily running lights may not work properly. If the above checks do not solve the problem, it is recommended to go to a professional repair shop to use diagnostic tools to detect the control module, and replace or repair it if necessary.
Professional maintenance
If the problem cannot be solved after their own investigation, it is recommended to seek the help of professional maintenance personnel to ensure that the daily running lights return to normal and ensure driving safety.
Through the above steps, you can gradually troubleshoot and solve the problem that the daily running light is not on. If the problem is complex or involves professional equipment, it is recommended to contact professional maintenance personnel as soon as possible.
