Setting requirement: It usually automatically turns off after about 30 seconds delay. Additional information is as follows: 1. Daytime running lights: Mostly equipped with higher brightness LED configurations, which can significantly reduce power consumption by up to 35%, extend battery life, and have a maximum lifespan of up to 8000 hours, almost equivalent to the vehicle's service life. 2. Advantages of daytime running lights: From the perspective of the surrounding environment, dedicated daytime running lights can improve visibility while making motor vehicles more prominent.
