How can you tell whether the rear fog lamp is switched on?

To determine whether the rear fog lamp is switched on in a vehicle, you primarily look for the amber indicator light. This light informs the driver that the rear fog lights are activated. While the blue indicator light indicates that the high beams are on, and the red indicator light signals other critical issues (like brake failure), they are not related to the operation of rear fog lamps.

In Germany, it's crucial to pay attention to these indicator lights because they ensure that your lights are functioning correctly and help communicate your vehicle's status to other drivers. Understanding these signals can enhance road safety, especially in low visibility conditions where fog lamps are necessary.
