Indicator Light
An Indicator Light, which is attached to most powered buildings. Displays the operating state of the building.
Height	2 m

Indicator Lights are tube lights situated on electricity-powered and generator buildings that reflect the building's operating state. There are five total operating states they can display. Indicator Lights have a hitbox and cannot be walked through, but structures such as Walkways can be built through them if they aren't within the hitbox of a building.

Structures that lack Indicator Lights are:

• AWESOME Sink
• Nuclear Power Plant
• Power Storage, which has a charge indicator on its side instead
• Freight Platform and Fluid Freight Platform
•  Lights
• Crash Sites

The Radar Tower has three Indicator Lights, the only building to have multiple. All lights display the same color.

States

Color		Meaning	Cause
	Red	Unpowered	Power is not being supplied (production buildings) The recipe is not configured (production buildings) Power Line connection is missing (generators) Power generator is out of fuel or Water
	Yellow	Standby	Insufficient materials are present in the machine to operate (the building is starving for resources, production buildings) The output slot or fluid tank is full (the building has backed up) The building is manually set to standby mode with the standby switch Miner is powered but has depleted a SAM Ore resource node Hyper Tube Entrance is powered but not connected to a Hyper Tube Pipeline Pump is powered but fluid is not flowing through; or is placed on a Pipeline containing a gas The Pump is not connected to a Pipeline on both ends There is no fluid to be moved or nowhere to move it to Head lift is exceeded Jump Pad has been used in the last ~2 seconds
	Green	Operating	The building is powered/fueled and working (executing a crafting, extracting or burning cycle) or awaiting vehicles to serve
	White	Overclocked	Same as the green state, but the building has a Power Shard inserted (it does not need to be actually operating overclocked) The only state of the Power Switch that does not actually correspond to overclocking
	Blue	Bugged	This state only appears on unfinished or improperly implemented buildings, it cannot occur during normal gameplay Presumably the default state when the light isn't set to react to the condition of the building It could be seen in some old UI icons of buildings and some official game trailers

Note: the "white" state has a slightly bluish tint, it is not to be confused with the "blue" state, which appears blue-indigo.
