Otis RGB Lantern

This video shows a detailed look at a rather interesting elevator direction lantern. This lantern can be programmed to light up different colors for each direction.

Each arrow's color can be programmed by changing the R, G, or B switches for each arrow. From there, the intensity of each color can be adjusted. The lantern in not true RGB since each arrow is not totally independent, but the color options are a lot more than a typical lantern.
