The mod works with an HDR it replaces the default HDR in priority 16 when the night vision is turned on and then is replaced again by the default HDR when they are turned off.
The first problem: On Xbox the HDR is very bright much more than on PC. You can try with the binocular symbol from the GameMaster mode.
The second problem: On Xbox when the player equips a helmet with night vision he has to press RB+Right Pad to turn on the night visions or turn them off. For them nothing happens.
