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. 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.

Power consumers or generators that lack Indicator Lights are:

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