Learn how to make lights flicker realistically in After Effects using a single expression — perfect for haunted scenes, old film looks, emergency lighting, neon signs, and cinematic atmosphere.
In this tutorial you'll use the wiggle expression to create random, organic light flicker without drawing a single keyframe. You'll learn how to control the speed and intensity of the flicker, apply the same expression to multiple lights, and combine it with other effects for a polished, professional result.
Topics include: After Effects expressions, the wiggle expression, light flicker effect, animating lights in After Effects, expression-driven animation, and cinema-style lighting effects.
