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:

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

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

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.
