Hadan idea that popped into my head, but what if the current goggles also worked for night vision as well when the lights are out? You would receive extra vision range or obtain the radar tower 'senses' like he thing has. The goggles are nice to have in game already but I feel this mechanic would both make sense with the item in general as well as give reason to actually take the goggles over highly sought after grenades (in most cases I would opt for a nade over goggles).
Just a thought.
