Power redstone lamps via redstone and a lever. Turn the lamps on, and shoot a flaming arrow in them. When you turn the signal off, the arrow will fall a notch downwards when they should stick in and not move.

Oh okay. This one does happen.
Shooting at an off-state lamp and turning it on causes it so snap to the top of the block. Turning it off again makes it fall off completely.
Confirmed.
