In one to two sentences, explain how we can trace holiday lights back to technological advancements in the Cold War.

In that period, specifically 1962, the Light-Emitting Diode (which has variants of red, blue and green that can be combined to produce the most perceptible colours, usable as holiday lights) was as invented.
