- the lighting unit usually includes one or more lights, which, unlike in the prior art, are not arranged separately from the washer fluid container, but are integrated directly into it.
- the lighting unit is used to illuminate the surroundings of the vehicle or to identify the vehicle in unfavorable visibility conditions, for example in the dark or in bad weather.
- the washer fluid container has a shape that is specifically adapted to the shape of the lighting unit to be integrated, preferably depressions or Mounting holders into which the lighting unit can be inserted.
- the mounting receptacles preferably form, figuratively speaking, recesses in the wall of the washer fluid container or Bushings through the wall of the washer fluid container, through which the lighting unit or individual lights of the lighting unit are separated from the interior of the Wiper fluid reservoir can be contacted.
- the mounting range of the washer fluid container is advantageously expanded in comparison to a conventional washer fluid container, because the washer fluid container can be arranged, unlike in the prior art, at the position intended for the lighting unit. Furthermore, the degree of freedom in shaping or Arrangement of the lights in the lighting unit. For example, the lights can be arranged horizontally, vertically or diagonally. Particularly advantageously, the integration of the components mentioned allows a compact design, so that space is created in a front area of a vehicle, preferably a rail vehicle, in particular in a front area of such a vehicle, for additional components. In particular, space is created there for components that are required for automated driving.

- the washer fluid container comprises a cooling unit arranged in the interior of the washer fluid container with contact to the lighting unit for cooling the lighting unit.
- the cooling unit can absorb and dissipate heat energy generated by the lighting unit, so that the lighting unit does not heat up too much.
- the cooling unit preferably has a heat dissipation system for discharging heated air.
- the heat dissipation system is preferably integrated into the washer water tank.
- the washer fluid container preferably comprises a mounting receptacle in which the heat dissipation system is arranged.
- the heat dissipation system can, figuratively speaking, form a heat transport path which is guided past the lighting unit in order to absorb heat from the lighting unit and dissipate it from the washer fluid container.
- the cooling unit comprises a heat dissipation system, which has an air duct system with an air inlet for sucking in cool air and an air outlet for discharging heated air.
- the air duct system is preferably integrated into the washer fluid tank.
- the washer fluid container includes a tunnel-like mounting receptacle in which the air duct system is arranged.
- a kind of "draft" can be created via the air duct system, i.e. an air flow that can be sucked in via the air inlet, is directed past the lighting unit, absorbs heat from the lighting unit and leaves the washer water container again via the air outlet.
- the air duct system of the accessory device preferably comprises a first air duct with an air inlet for sucking in cooling air.
- the first air shaft serves to collect cooling air from the area surrounding the washer fluid container. This cooling air is then led past the lighting unit to be cooled, where it heats up, and it is then led out of the air duct system. This creates a so-called chimney effect, which creates the necessary negative pressure in the area of the first air shaft to suck in the cooling air and move the cooling air through the air shaft system. This advantageously means that no additional fan is required to draw in fresh cooling air.

It is therefore advantageous to lead the cooling second air shaft directly past the high beam, which generates particularly heat, in order to efficiently dissipate the heat generated.
- the cooling second air shaft preferably runs, preferably in a vertical direction, past the high beam of the lighting unit in order to particularly effectively cool the high beam, which generates a lot of heat, and to use the chimney effect of the warming, upwardly rising air and thus on the Installation of an additional fan or other active means for generating air movement in the air duct system can be dispensed with.
- the first air shaft of the air shaft system of the accessory device according to the invention which includes the air inlet, is connected to the second air shaft and, due to the mentioned chimney effect of the second air shaft, sucks in cooling air, which is supplied to the second air shaft and is guided past the lighting unit. There the sucked-in air heats up and is led out of the washer fluid container via the air outlet of the second air shaft.
- the first air shaft is preferably arranged horizontally on the floor on the inside of the washer fluid container.
- the first air shaft is advantageously located lower than the second air shaft, so that warming air can rise in the second air shaft and cooling air is sucked in from the first air shaft into the second air shaft by the chimney effect.
- the washer fluid container of the accessory device according to the invention comprises a device that leads from an outside, preferably the back of the washer fluid container, through the interior.
- Cable feed arranged in the interior of the washer fluid container to the lighting unit to supply the lighting unit with electrical power.
- the cable feed can be inserted into a tunnel-shaped recess in the washer fluid tank, similar to the cooling unit.
- the cables are advantageously protected from damage caused by external influences due to their integration into the washer fluid tank.
- the cables are protected from contact with the washer fluid in the washer fluid container by the preferably waterproof cable feed that surrounds them.
- the accessory device according to the invention preferably has fastening options for a mounting plate for additional components that can be mounted on the outside of the washer fluid container, preferably for automated driving. Additional components, in particular components that are used for automated driving, such as sensors, can advantageously be mounted on the washer fluid container in a space-saving and resource-saving manner.
- the lighting unit is arranged on an end face of the washer fluid container.
- the front side of the washer fluid container should be understood as the front of the washer fluid container when the washer fluid container is properly arranged in a vehicle, in particular the front area of the vehicle.
- the air ducts and the cable feeds simultaneously serve to stiffen the washer fluid tank or the accessory device, so that increased stability of the accessory device is achieved.
