The term 'Flicker of Light' can be summed up with the word 'GLINT, ' which is a five-letter word. A GLINT is a brief sparkle or flash of light, usually caused by the reflection of light off a shiny surface. It is often used to describe the twinkle in someone's eye, or the sparkle of a diamond. A flicker of light is a more sustained version of a GLINT, and is often used to describe the flickering of a candle flame or the flicker of a television screen.
