The relay provided is used to interrupt the voltage supply to the daytime running lights when the vehicle’s main lights are switched on. The relay is, therefore, fitted between the lights and the voltage supply.

When the position (side) light is switched on, voltage is supplied to the relay coil, which opens the circuit and interrupts the power supply to the daytime running lights. For this, the relay requires a respective signal, which is simply taken from the main headlight plug with the aid of a splice connector and fed to the relay. The cable of the standard position light must be used for this (terminal 58). At this point, route all cables to the relay and connect according to the Hella circuit diagram in the instructions.

Tip: Test the function of the daytime running lights now, as any problems are easier to eliminate at this stage.
