HUD/UI Tracker icon over objective making?

Hi. What is the way to do a target marker icon over an actor in the scene? I have a racing cenario and I want to make a visual cue to orient a player towards the next checkpoint. So it should be visible on screen at all times. I am using this https://www.youtube.com/watch?v=VJj6rQpktyI tutorial to make my checkpoints.
