weapon lamp is by default "L" to switch on/off but i noticed that this doesnt work with attached lamps to a gun. Also bipods should be needing a way to quick take down/up the legs. theres not mush time in a firefight to enter inventory to get the bipod down. I think it could be an idea to maybe drag down the bipod to the quickbar and by pressing that button the bipod takes it legs up or down. Maybe that the bipod has a smart system so it takes the legs up/down for itself when prone or resting weapon against an object if you will add weaponresting. Would be really nice. Also I think it should be possible to attach a lamp by using ducttape and a ordinary torch.
