How can you detect your indicator is defective?

To detect if your indicator is defective, two methods are particularly important according to German traffic regulations.

First, if the indicator control lamp flashes faster than normal, it usually indicates a malfunction in the indicator circuit – this is a key sign that one of the bulbs might be out.

Second, performing a functionality test before moving off is crucial for ensuring that all your indicators are working properly. This proactive check helps prevent potential hazards on the road.

The option regarding the control lamp being permanently illuminated red generally refers to a different issue that might not specifically indicate a defective indicator functionality. Thus, the correct combination underlines the necessity of both monitoring the flashing rate and conducting a pre-driving check for safe driving practices.
