Pick up flashlight with "E" ?

Hey guys. I really need help. I'm just stuck here. What I want to do is come to an object, click E on it, and do it so that it activates my spotlight, and the object destroys itself. I even googled this, but somehow everything I found, didn't work for me.

So how I think it should work:

The script checks if the player is in trigger If player is in trigger and presses E the script activates my light and destroys the object.

Just wondering how I should go on about it ?
