Although it is an electrical component, it has the ability to stop working due to environmental factors, thus it should last the lifespan of your car. You will need to have one of our skilled technicians replace it if it does break.

What is Audi A4 DRL?
The quest for the ideal Daytime Running Light (DRL) goods for your Audi A4 is now done, which will make it happy. For your car, Advance Auto Parts provides 12 distinct Daytime Running Lights (DRL) available for in-store pickup or shipment.
Can I switch to LED daytime running lights?
Yes, LED bulbs can be used as DRLs, but you must make sure they are suitable with your vehicle, installed correctly, and dimmed at night to avoid dazzling other drivers. To prevent flickering, you might additionally require other parts like a resistor or CANBus converter.
There are several things to ensure you get correct, so I’ll outline them here:
- Why using LED daytime running lights properly makes them safe
- What to take into account while using LED lights as DRLs
- Possible reasons why your lights are flickering
- The materials required to assemble an LED bulb for use as a DRL
The sensor for daytime running lights is where?
It’s simple to check if your headlights, fog lights, or taillights are broken. To check if they are operating, you simply turn on the switch. However, the switch for the daytime running lights is not always present. If the weather is not sunny, checking the DRL is the simplest task.
Examine the ambient light sensor.
The dash contains the ambient light sensor. It utilizes automatic lighting features, reads the ambient light, and determines whether to switch on the headlights or the daytime running lights depending on how dark it is outside.
The sensor, which may or may not be in the center of the dash, resembles a half-dome.
Make sure there are no obstructions blocking the ambient light sensor by checking. If something is blocking it, the sensor won’t be able to detect the light, the DRL won’t function, and the headlights will wear out more quickly as a result.
If it’s not sunny outside, shine a very strong light on the sensor to examine it. A flashlight could still be required if bright lights inside a building or in a place like a garage are insufficiently bright.
Check to see if the headlights are off with the key turned on and the flashlight over the sensor. When there is light on the ambient sensor, the headlights shouldn’t switch on, indicating that the sensor is functioning.
With a helper, check to see if the DRLs are on.
When the transmission is in Drive, Reverse, or Neutral, the DRL will activate. Having a helper keep an eye on the headlights while you are doing this is beneficial. Chock the wheels if you don’t have a helper to prevent the car from rolling away.
For the DRL to turn on in some vehicles, the engine must be running, while in others, the e-brake must be released.
Check to determine if the DRL are functioning while the car is in an environment where they will activate.
Check the bulb, socket, and switch if only one DRL is functioning.
One daytime running light that is the only one not functioning most likely has a burned-out bulb or a faulty switch. If the bulb is black or the filament is burned out, which indicates that it needs to be changed, remove the socket from the lamp.
Check to determine if the socket burned or melted because DRL can operate for a very long time; if so, replace it. Check for melting at the bulb’s contact point.
