Abstract
In a rear combination lamp assembly for a vehicle, a plurality of LEDs capable of being turned on and off independently of each other are mounted on a first printed circuit board. A plate-like lens element and a second printed circuit board are arranged with the first printed circuit board located between them. A control circuitry is mounted on the second printed circuit board, for selectively turning on and off the LEDs to display various patterns on a matrix display formed by the LEDs. The first printed circuit board, the lens element and the second printed circuit board are held in a united fashion.
