Since the system is the same with 37-116....
The glass (or clear plastic) cylindrical rod in front of the light is a lense, so if the distance is off or the glass is murky the light will dissipate instead of focusing in a thin vertical line.
Troubleshooting is easy - see where the light stops.
Unlike electrons, light is visible
