The present invention relates to a multifunctional internal lighting device for a motor vehicle. A single internal lighting device comprises various LED-type light sources which are capable of performing at least one first internal lighting function and a second internal lighting function. The various LEDs are distributed into at least two separate sets, a first set being dedicated to the performance of the first internal lighting function and a second set being dedicated to the performance of a second internal lighting function. In particular, it is proposed to use axial emission LEDs or through-emission LEDs and lateral emission LEDs to perform the first function and the second function respectively.
