The way I'm thinking that this could work is that there's a flashlight beam model mounted to the right hand, and there's a very fast-moving projectile with a small light mounted to it. The projectile would stop after a short distance, or if it hits a brick/wall. And additionally there could be a corona.png mounted to the hand, and you have to raise your hand by holding a gun or tool.
Need pls.
Sorry if it doesn't make sense, I'm not good at describing things :x
