Lumar plate

The Lumar plates are blocks added by RedLogic which can be used as pressure plates, buttons, or indicator lights by interacting with redstone signals. The plates can be placed on any block face. There are variants for each of the 16 standard colors.

When used as buttons or pressure plates, the plates emit a redstone signal if a player presses or steps on the plate. When used as indicator lights, the plates switch the light on/off if a redstone signal receives the plate.

With the Screwdriver and crouching the player can switch between following modes:
 * Default: If the button is activated or a signal receives the plate, the light goes out.
 * Inverted: If the the button is activated or a signal receives the plate, the light goes on.
 * Always on: The light is always on.
