A light and sound system for a bowling pin deck includes a controller interposed between a music system and a light assembly connected to a forward end of a pin setter assembly and positioned forwardly and above a bowling pin deck. The light assembly includes a rearwardly and downwardly projecting light arrangement of colored and infrared LEDs mounted upon a light plate. Positioned above the light plate is a standard fluorescent bulb for uniform traditional illumination of the pin deck. The LEDs are configured and positioned for full illumination of the pin deck in various colors including red, green and blue, which are illuminated by a controller either independently of or in conjunction with the music system. During all periods, the infrared LEDs are illuminated to operate in conjunction with the automatic scorer.
