If you have a car with parking sensors and mount extra lights on a holder, front bar or similar, there is a risk that the parking sensors will be interfered with. This PDC cushion acts as a sensor extinguisher and does not require any intervention on the car, but is mounted in front of the parking sensor. The PDC pad ensures that the signal bounces back to the sensor, causing it to turn off. 

Normally you only need to cover 2 of the 4 sensors at the front. If the sensors are still alarming, it is usually because the PDC pads have not been installed correctly.
