Filling level indicators for washer fluid containers in motor vehicles have hitherto been arranged directly on the washer fluid container or been integrated in the instrument cluster on the motor vehicle. Despite the available information, the filling of the container when the level is too low is often delayed. A filling level indicator more effectively indicates the filling level by arranging the filling level indicator in the region of the tank filler neck, whereby the filling level in the washer fluid container is only indicated to the driver when he has in any case interrupted his journey in order to fill up with fuel and is free from other activities, so that it is virtually impossible for him to be distracted.

1. A filling level indicator for a washer fluid container in a motor vehicle, said indicator being located at a tank filler neck of a fuel container of the motor vehicle to be visible to a person directing fuel to the filler neck of the fuel container, said indicator having an indicating element and at least one light source, the indicating element being connected via a control unit to a filling level sensor disposed in the washer fluid container, wherein the filling level indicator is distant from the washer fluid container, and the at least one light source illuminates the indicating element at a time when the filler neck is to receive fuel. 2. The filling level indicator as claimed in claim 1, wherein the filling level indicator (5) comprises at least one light guide (17, 17') which is arranged between said light source (9, 9') and the indicating element (10). 3. The filling level indicator as claimed in claim 1, wherein the light source (9, 9') is an LED or a bulb. 4. The filling level indicator as claimed in claim 1, wherein the light source (9, 9') is a light source which emits at least two different colors. 5. The filling level indicator as claimed in claim 1, wherein the indicating element (10) is made of a transparent material. 6. The filling level indicator as claimed in claim 1, wherein the filling level indicator (5) is connected to a switch (11, 19, 20). 7. The filling level indicator as claimed in claim 6, wherein the switch is a reed contact (19) or an actuating element (11) in a passenger compartment of the vehicle (1). 8. A filling level indicator for a washer fluid container in a motor vehicle, said indicator being connected via a control unit to a filling level sensor arranged at a tank filler neck of a fuel container of the motor vehicle, and comprises at least one light source (9, 9') and at least one indicating element (10), wherein the light source (9, 9') is arranged in or on an actuator (13) for a tank-flap lock and the light source in connection with the actuator for the tank-flap lock builds a structural unit. 9. A filling level indicator for a washer fluid container in a motor vehicle, said indicator being connected via a control unit to a filling level sensor arranged at a tank filler neck of a fuel container of the motor vehicle and comprises at least one light source (9, 9') and at least one indicating element (10), wherein the light source (9, 9') is arranged in a tappet (16) of an actuator (13). 10. The filling level indicator as claimed in claim 9, wherein the indicating element (10) is arranged in or on the tappet (16). 11. A filling level indicator for a washer fluid container in a motor vehicle, said indicator being connected via a control unit to a filling level sensor arranged at a tank filler neck of a fuel container of the motor vehicle and comprises at least one light source (9, 9') and at least one indicating element (10), wherein the indicating element (10) is fastened next to the tank filler neck (8) on vehicle body (12) or a tank flap (6).
