There are lights within both vents, similar to the Hall Lights in the original Five Nights at Freddy's. These are triggered by a single button above each respective vent, allowing the player to spot any animatronics who might be poking their head into The Office from there.
Unlike the first game, however, these lights do not drain power, as there is no power limit for the building. They also do not emit a sound upon discovering an animatronic.
It's worth noting that the lights do not need to be clicked a second time to turn them off. The buttons now have a click-and-hold functionality. Also, the player does not need to click on the button itself, as it is possible to have the mouse button pressed as the cursor passes onto the button, which will turn on the light in the same way.
- Withered Bonnie enters exclusively through the Left Air Vent. This is similar to how Bonnie entered the Office in Five Nights at Freddy's, which was exclusively through the left door.
- Curiously, when Balloon Boy appears here on both the camera and light, his sign and balloon vanish, but when he enters The Office, they reappear with him.
