Daytime running lights make the vehicle to be identified when running on the daytime. That is to say, we have the lamp to let others know that there's a car coming, not to let the driver see the road more clearly. So the Daytime running light is a kind of signal lamp.

The car system will automatically close the LED daytime running lamp when the headlight is on. If you want to turn off the LED Daytime running light, you have to connect it to the trip computer, then you could turn it off from the inside computer of the car.
