Description

TECHNICAL FIELD OF THE INVENTION The technical field of the invention is that of lighting assemblies for motor vehicles (passenger cars or commercial vehicles). The lighting assembly may, in particular, be capable of providing lighting and/or signaling functions. The present invention relates in particular to removable light assemblies, especially those located at the front or rear of the vehicle. TECHNOLOGICAL BACKGROUND OF THE INVENTION Currently, motor vehicles are equipped with front and rear lighting assemblies, either to illuminate the road or to be visible to other drivers. These assemblies consist of one or more light sources housed in a hermetically sealed casing. Given the conditions of use, it is essential that the assembly be watertight to prevent water from reaching the light sources. Consequently, in the event of an accident resulting in damage to part of the assembly or a malfunction, such as a light source or an electronic component, the entire assembly must be replaced, increasing the repair cost for the user. The document OF 10 2019 218 671 A1 describes a luminous ensemble following the earlier art. SUMMARY OF THE INVENTION The invention offers a solution to the problems mentioned above, by allowing only the damaged part of the assembly to be replaced, rather than the entire assembly. The invention is described in claim 1. More particularly, the invention relates to a lighting assembly intended to be mounted on a motor vehicle and comprising: a main casing comprising a first side with a front opening and a second side, opposite the first side, with a rear opening arranged opposite at least part of the front opening, a lighting device with a secondary housing, a glass panel sealing the front opening on the first side of the main casing in a watertight manner, It is characterized in that the lighting device is positioned opposite the rear opening on the second side of the main housing, and the secondary housing is fixed in a watertight and reversible manner to the second side of the main housing. The front opening preferably extends across the entire front surface of the main housing. In the event of a component failure within a lighting device of a lighting assembly, and/or in the event of impacts causing damage to part of the lighting assembly, the lighting assembly according to the invention allows for the replacement of only a portion of the assembly: for example, only the lens and the main housing, or only the lighting device itself, can be replaced, while ensuring the assembly remains watertight before and after the repair. This reduces repair costs. The opening on the second side, opposite the first side, allows the lighting unit to be brought back to the main housing, particularly thanks to the attachment of the secondary housing to the main housing. This is especially advantageous if the main housing is irreversibly sealed on the first side by the glass. The invention also allows for a certain degree of standardization because the same main housing with its glass from a given lighting assembly can be used with different lighting devices depending on the vehicle's equipment level. Advantageously, the lighting device is housed in the rear opening on the second side of the main case. Advantageously, the glass is irreversibly fixed to the main casing. The glass can, for example, be glued to the main casing. Advantageously, the secondary housing includes a groove in which a sealing gasket is positioned opposite the main housing. This gasket ensures a watertight seal between the two housings, in particular between the secondary housing of the lighting device and the main housing of the lighting assembly. Advantageously, the lighting device includes a means of attaching the secondary housing to the main housing. This attachment means will, for example, consist of tabs placed on the secondary housing into which fixing screws can be inserted, which in turn fit into complementary attachment means. like screw barrels, placed on the main housing. When the fixing screws are tightened, they compress the sealing gasket on the main housing, thus ensuring the watertight fixing of the secondary housing, and therefore of the lighting device, to the main housing. Advantageously, the secondary housing is open on one front face, and the glass closes the front face of the secondary housing. Indeed, since the secondary housing is hermetically sealed to the main housing, and the glass seals the front opening of the main housing, the glass contributes to the airtight seal of the front face of the secondary housing. Specifically, the front face of the secondary housing is not attached to the glass; that is, the front face of the secondary housing and the glass are not in contact. The glass thus contributes indirectly to sealing the front face of the secondary housing. Advantageously, the lighting device comprises a light source and an optical deflection element, such as a reflector, lens, or light guide. Th
