Indicator Lights are tube lights situated on electricity-powered and generator buildings that reflect the building's operating state. There are four total operating states they can display.

Power consumers or generators that lack Indicator Lights are:

• Nuclear Power Plant
• Particle Accelerator
•  Lights
• Crash Sites

Some buildings have non-standard ways of displaying their state:

• AWESOME Sink has numerous light fixtures that light up whenever the Sink is in operation
• Freight Platform and Fluid Freight Platform have an icon on both sides of the crane, which light up when the platform is properly connected to a Train Station
• Power Storage has a charge indicator on its side

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

States

Color		Meaning	Cause
	Unlit	No Connection	Building is not connected to a Power Line Production building has no recipe configured
	Red	No Power	Building other than a power generator has no power supply The grid it is connected to is either has no operating power generators or is tripped Power generator is out of fuel or Water
	Yellow	Standby	Production building is starving for resources by not having enough materials in its input slots Building has backed up resources in its output slots Building is manually set to standby mode by clicking the standby switch in its UI 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 Hyper Tube Entrance is not connected to a Hyper Tube Jump Pad has been used in the last ~2 seconds Truck Station doesn't have any vehicle docked under it Miner has depleted a SAM Ore resource node
	Green	Working	The building is operational, such as by crafting, extracting, producing power, or otherwise executing its function
	White/Blue	Overclocked	Same as the green state, but the building has a Power Shard inserted (it does not need to be actually operating overclocked)

Notes

• Production buildings refers to buildings with configurable recipes
• The "overclocked" state appears white on high gamma values and light blue on low gamma values

Trivia

• Indicator Lights were not named until the 0.5.0.2 patch notes, where they were named "Building Status Indicator Lights". 0.5.0.10 patch notes refer to them as "Status Indicator".
• There is an "indigo blue" state which only appeared on unfinished or improperly implemented buildings.
