Hi-Tec Art produces a generic maker kit with LEDs, and LED Chess and Checkers sets sort of like a proof-of-concept. Not the first LED chess set.

It seems to work something like a Lite Brite. The set comes in two variants: a larger Masterpiece version and a smaller Sketch version, and can also come in just the pieces and plastic board overlays if you already have the hardware.
