"Trailer tentacles" to show the trailer's position
I often have to hook up the trailer to my car.
Sometimes I transport my boat on it, which makes the trailer very heavy and rigid and it may damage the coachwork if I don't position the car exactly right.
I built a little helper with a few magnets - the "trailer tentacles" - which are long, flexible rods with little red flags on the top that I attached to the car and the trailer to show the relative position of the trailer to the car.
I sell these trailer tentacles.
