A multi-function vehicle light assembly (MVLA) that incorporates in a single enclosure a plurality of LED modules. Each module produces a white light that indicates that a vehicle is in reverse, an amber light that indicates that a vehicle is making a right or a left turn, and a red light that functions as a vehicle tail-light and to indicate that the brakes are being applied. Two embodiments are disclosed, in the first embodiment the plurality of LED modules directly produce a set of white, amber and red lights. In the second embodiment an LED module is utilized that includes blue, green and red LEDs that are selectively combined by an LED control circuit to produce the white, amber and red lights. Each embodiment also includes a set of control units for selecting which of the input signal lines are to be activated.
