How to Activate Daytime Running Lights on a 2010 Audi?

[StElliana]

Some models of the 2010 A4L are equipped with daytime running lights (DRLs), which automatically turn on when the engine starts during daytime driving. They are controlled by the power controller. At night, when the headlights are turned on, the DRLs will automatically turn off. Here are the details: 1. The purpose of daytime running lights: They are lights that make the vehicle more noticeable during daytime driving. Their function is not to help the driver see the road but to signal to others that a vehicle is approaching. Therefore, these lights are not for illumination but serve as signal lights. 2. Reducing accidents: Installing daytime running lights can make a car look cooler and more stylish, but their primary benefit is not aesthetic—it's about improving the vehicle's visibility. Studies abroad show that using DRLs can reduce vehicle accidents by 12.4% and lower the fatality rate in crashes by 26.4%.
