Flashlight like p.t

I’m trying to make a flashlight system like that of p.t. Basically i’m trying to give the light a small delay when the camera moves. For example: If the player looks to the left a little bit, there will be a slight delay before the flashlight moves to where the player is looking. I think this further immerses the player into the world. I say p.t because the only games that use that effect (that I know of) are p.t and Resident evil which the demo just came out recently, and almost the entire gaming community knows what p.t was. Thx For all answers.

Have you tried attaching the light to the Spring Arm and enabling Camera Lag?
