Items such as the flashlight and binoculars require scripts to activate their use. For example, there are dozens of flashlight scripts all over the forums which work by using the torch entity as something to be picked up and will allow you to, say, press the "f" key to activate a torch effect. But vanilla FPSC doesn't support the actual 'realistic' uses of these items.. Yet.
So, if you want a flashlight to work, search the forums, there's many to choose from, as well as many FPSC mods that come with the feature. I'm sure there are also binocular features too, though I can't recall coming across any..
