Stage Lights

As a version of more lighting, stage lights can be introduced. Hypothetically, the actual block permeates a light that reaches a far longer distance than other forms of lighting, in a single direction that the stage light is facing. When this light strikes a wall, it creates a 5 (or more) block radius of light. There could be a light for each corresponding color in Minecraft.

Perhaps more difficult, the stage light could constantly move in certain directions, changed when you use the left trigger on the origin block, much similarly to an armor stand which can change poses.
