A device for positioning a lighting body of a vehicle, such as a headlamp or a fog lamp, comprising: a case with an articulated light module arranged therein, such as a light source or a reflector of the lighting body, said module being rotatable about a centreline thereof which extends approximately horizontally and/or approximately perpendicularly to the direction of the luminous flux, when the device for positioning a lighting body is mounted to the vehicle, and a device for positioning the light module, wherein the device for positioning the light module with respect to a horizontal centreline of the lighting body and, respectively, with regard to the ideal direction of the luminous flux is arranged on said case, said device for positioning the light module is formed of at least two actuators (8, 9) set at an angle with respect to each other and mutually cooperating, and a follower associated with said light module, wherein said follower is formed with a fork-like structure comprising threaded plates (19, 20) that extend mutually in parallel and are spaced with regard to each other and are attached at the first end thereof to a base of the follower, said threaded plates (19, 20) being formed in the region of cooperation with a threaded section of the at least one of the actuators (8, 9) with a threaded section, which comprises an internal thread provided for cooperation with an outer thread of the threaded section, characterised in that each said threaded section comprising the internal thread is formed on an arc a centreline thereof approximately corresponds to the horizontal centreline of the lighting body and, respectively, to the centreline of the light module, the latter is to be rotated about and wherein said arc lies in a vertical plane extending through the centreline of the threaded section and in parallel with the threaded plates (19, 20), when the device for positioning a lighting body is mounted to the vehicle, wherein said threaded section which is provided in the forklike structure is configured to compensate movements over the circular arc and ensures, in each position of the fork-like structure relative to the actuator, a constant contact in several threads between the outer thread of the threaded section and the inner thread of the fork-like structure within the required positioning region of the light module. a case with an articulated light module arranged therein, such as a light source or a reflector of the lighting body, said module being rotatable about a centreline thereof which extends approximately horizontally and/or approximately perpendicularly to the direction of the luminous flux, when the device for positioning a lighting body is mounted to the vehicle, and a device for positioning the light module, wherein the device for positioning the light module with respect to a horizontal centreline of the lighting body and, respectively, with regard to the ideal direction of the luminous flux is arranged on said case, said device for positioning the light module is formed of at least two actuators (8, 9) set at an angle with respect to each other and mutually cooperating, and a follower associated with said light module,
