The rain/light sensor from HELLA convinces with impressive technical data

The rain and light sensor for trucks illustrates once again the pioneering spirit of HELLA, as this was the first sensor offered on the market in this combination.

The combination sensor can detect rain and automatically controls the windshield wipers (rain sensor). The sensor also automatically enables headlamp mode (light sensor).


This complete solution offers truck customers with the unique option of using both rain and light functions in one single sensor.

This sensor is also user-friendly. This is illustrated, for example, through its automatic activation of the windshield wipers and - depending on the rain conditions (i.e. drizzle vs. strong rain) - its harmonious windshield wiper movements. The large, uniform measuring range of the sensor, which is especially important for trucks, ensures optimum sensitivity with regard to activating the windshield wipers, as well as consistent wiper behavior.

Similarly, as a driver assistance system, the sensor's light function provides the option of automatically switching headlamps and rear combination lamps on and off (e.g. when driving through tunnels or underpasses) and controlling the instruments on the dashboard.
