A lighting assembly for a reel slot machine includes an interface board and a flexible printed circuit board (PCB). The interface board is substantially planar, electrically couplable to the reel slot machine, and includes a first electrical connection plug and a second electrical connection plug spaced from the first electrical connection plug. The flexible PCB defines a first end and a second end, the first end and second ends of the flexible PCB are electrically coupled to the first electrical connection plug and the second electrical connection plug, respectively. The flexible PCB bows away from each of the first and second ends to define a bowed primary face facing away from the interface board. The flexible PCB further comprises a plurality of light sources coupled to the bowed primary face. During use, the plurality of light sources selectively illuminate to provide lighting to a reel of the reel slot machine.
