Pip-Boy 3000 light

The screen on the Pip-Boy 3000 can be used to illuminate the screen to a level that is sufficient to light the area immediately around the user, acting as a makeshift lantern in darkened areas.

To activate the Pip-Boy Light, hold down Tab, you can deactivate it the same way. Hold B to activate and deactivate the Pip-Boy Light on the Xbox 360 and hold down O to activate on PS3.
