There working for me bud, try taking the helmet off and putting it back on and make sure there's a good battery in it then hold RB the option is at the top of the wheel.

I have the same issue, I’ve logged multiple times and even tried a different helmet and it still doesn’t work

Equip the NVGs to your helmet or NVG headstrap. Then quickslot it to your left or your right. Then quickslot the NVGs to the bottom of your quick wheel. It should show Toggle on the Top quickslot. Press Toggle option, there it should turn on the NVGs with a battery equipped in the goggles.

Same here

Got it. Had to have both nvg and light for the option to appear.
