1. A method employing a hit indicator system to indicate that a target has been struck by a projectile, the method comprising:
receiving a signal from an impact sensor;
processing the signal; responsive to the processing, activating a light source to output light based upon a determination that the signal includes a value that is above an impact threshold; redirecting the light from the light source through a light redirection element, wherein the redirecting comprises:
accepting the light from the light source at a light intake surface of the light redirection element;
passing the light through a continuous translucent material; and
reflecting the light via a reflection surface, wherein the reflecting comprises positioning the reflection surface to form an angle that is selected to cause the light received through the light intake surface to be reflected within the continuous translucent material to a light output surface; and
projecting the light from the light output surface toward a source of the projectile as an indicator that the hit indicator system detected a hit.
