What is the role of car running lights
The main function of Daytime Running Light (DRL) is to improve the visibility of vehicles during daytime driving, thereby enhancing driving safety. The following is its specific role:
Improved vehicle recognition
Day lights make it easier for other vehicles and pedestrians to spot your vehicle, especially in unstable light situations such as backlight, through tunnels, or in bad weather (such as fog, rain and snow).
Reduce the risk of traffic accidents
Studies have shown that vehicles equipped with daily running lights can reduce traffic accident rates and deaths. For example, European data show that daily running lights can reduce accident rates by 3% and death rates by 7%.
Enhanced safety in severe weather
In weather conditions with poor visibility, daylights can improve the visual distance of vehicles and help other traffic participants better identify vehicles, thereby reducing the risk of collisions.
Energy saving and Environmental protection
Modern daily running lights mostly use LED lights, low energy consumption, usually only 20%-30% of the low light, and longer life, in line with the requirements of energy saving and environmental protection.
Enhance brand image and aesthetic
The design of daily running lights is increasingly diverse, and many high-end models use them as part of the brand image, while also enhancing the overall beauty of the vehicle.
Automatic control and convenience
The daily running light is usually lit in sync with the vehicle start, without manual operation, and automatically turns off when the engine is turned off or other lights (such as low light) are turned on, which is easy to use.
It should be noted that daily running lights cannot replace low light or fog lights, because their lighting effect is limited and is mainly used to improve identification rather than lighting.
The main reasons for the failure of automobile daily running lights include the following :
Lamp damage : The lamp of the day running lamp may age or burn out due to long-term use or voltage fluctuations.
line problem : line aging, short circuit or poor contact will affect the normal operation of the running light .
switch failure : The switch of the daily running lamp is damaged or poor contact will also cause the bulb to not emit normally .
blown fuse : the fuse in the circuit short circuit or overload will blow, cut off the power supply, resulting in the day running light is not on .
guide halo driver fault : loose driver connector or poor connection will affect the working of the day running lamp .
headlight control module failure : the headlight control module failure will cause the daily running lights can not work normally .
Troubleshooting and solution :
Check the bulb : First check whether the light bulb of the day running light is damaged or aging, and replace the new light bulb if necessary.
Check the line : check whether the line is damaged, aging or poor contact, repair or replace the line in time.
Check the switch : confirm that the switch is working properly, replace or repair if necessary .
Check the fuse : confirm whether the fuse is blown, if necessary, replace the fuse .
Check the halo driver : check whether the driver connector is loose or improperly connected, and reinsert or replace the driver if necessary.
Check the headlight control module : confirm that the control module is working normally, if necessary, professional maintenance .
Preventive measures and routine maintenance :
Regular inspection : regularly check the bulbs, circuits and switches of the daily running lights to ensure that they are working properly .
correct use : Avoid the use of day running lights in an unstable voltage environment to prevent premature damage to the bulb .
