The indicator light is flashing much faster than usual. What could be the cause of this?

When the indicator light is flashing much faster than usual, it typically indicates a malfunction in the indicator system, most commonly due to a defective bulb. In German traffic regulations, proper functioning of vehicle lights is crucial for safety and communication with other drivers. If one bulb is out, the system compensates by increasing the flashing speed to alert the driver about the issue.

Additionally, it's important to note that if the hazard lights are switched on, all indicator lights will flash simultaneously, which can also lead to confusion in assessing the functioning of individual indicators. Therefore, when diagnosing a fast-flashing indicator, both the possibility of a defective bulb and the hazard lights being activated should be considered. This comprehensive understanding ensures that drivers maintain their vehicles in a safe condition, complying with regulations aimed at reducing accidents on the road.
