Air Vent Lights

Were you looking for the Hall Lights from the first game, or the Flashlight from the second or fourth game?

RightLightOffOn — Right Air Vent light button.

The Air Vent Lights are a vital in-game mechanic used in Five Nights at Freddy's 2. They are activated by pressing and holding the buttons labeled "LIGHT" (or tapping it in the mobile version) and are deactivated by releasing them.

Uses[]

The Vent Lights are used to alert the player of animatronics that are about to enter The Office via the air vents. Most of the animatronics who travel through the vents (Toy Chica and Balloon Boy in the Left Air Vent, and Toy Bonnie and Mangle in the Right Air Vent) are able to be exposed just before sneaking inside. Anytime the player sees an animatronic under a Vent Light, they are advised to equip the Freddy Fazbear Head.

Advantages[]

Allows the player to brighten each of the two air vents.
Gives the player the opportunity to counter Toy Bonnie, Toy Chica, Mangle, and BB with the Freddy Fazbear Head, as they will appear under the lights before entering The Office.
Unlike the first game, the animatronics will not enter The Office until the player puts up the Monitor. No matter how long the player stalls, the animatronic in question will not enter.
Unlike the Flashlight, the Vent Lights will not drain any sort of power reserve, so the player may use them as much as needed.

Disadvantages[]

Can be disabled by BB if he enters The Office.
Cannot be used while wearing the Freddy Fazbear Head or while the Monitor is up.
The Flashlight cannot be used while one of the Vent Lights is on.
Bonnie and Chica will not appear in these lights before entering The Office.

Trivia[]

The Vent Lights are the second game's equivalent to the first game's Hall Lights. They serve the same purpose and operate in a similar manner, revealing an animatronic while they are still in a blind spot just before it's too late.
Unlike the Hall Lights from the first game, the Vent Lights do not emit a sound upon discovering an animatronic, making it more difficult to notice the animatronic in the vent if the player doesn't pay attention.
- When disabled by BB, they will even make the same sound as the Hall Lights after Bonnie and/or Chica have disabled them.
Ironically, Bonnie and Chica, the only two animatronics who bypass the Vent Lights, were the only ones to be exposed by the Hall Lights in the first game.
Although Bonnie enters The Office from the Left Air Vent and Chica enters from the Right Air Vent (similar to their behavior in the first game), their toy counterparts swap these roles; Toy Bonnie only approaches via the Right Air Vent while Toy Chica approaches through the Left Air Vent.
