First stop: pop the top off the Nest button, the combination input switch and multi-colored sweeping light.
An ambient light sensor sits in the center of the button, with lenses in the translucent cover to increase its viewing angle.
A ring of RGB LEDs surround the sensor to make up the Protect's indicator glow:
White for the automatic night light
Reassuring green to indicate all's clear
Yellow for an early warning
Red for a get-out-of-town emergency
