Night Person

Night Person is a perk in Fallout 3, Fallout: New Vegas and Fallout 4.

Fallout 3 and Fallout: New Vegas
With this perk, the player gains +2 to both Intelligence and Perception (up to a maximum of 10) between 6:00 P.M. and 5:59 A.M. in-game time.

As this perk only gives a temporary increase to your statistics (unlike the Intense Training perk), it does not give an advantage when leveling up - there's no change to the number of skill points gained and the increased stats don't count for any perk requirements. Thus, the only effects are enhanced threat detection, Intelligence and Perception ability checks (in dialogue and elsewhere), and a bonus of +4 (or less if your Perception and/or Intelligence is already higher than 8) to Medicine, Repair, Science, Energy Weapons, Explosives and Lockpick.

Bugs
The night vision bonus may remain active while standing / during daylight hours (6:00 A.M and 6:00 P.M.). This causes the sides of the screen to be blurred when standing, and can cause things to be WAY too bright during daylight hours/indoors. Fixes (works on Console too):
 * Fix 1: While standing, go into your Pip-Boy, then into your skill tree, then back back out (sometimes just going into your Pip-Boy and backing out works).
 * Fix 2: While Standing, go to any container and enter the 'transfer' screen, then back out.
 * Force Bug to Happen: The bug may be manually activated by crouching, waiting for night vision to activate, then going into your Pip-Boy, backing out, and standing up (to test).
