How do you switch on the light on the Nerf night finder?

To switch on the light on the Nerf Night Finder, locate the small switch or button usually found near the trigger or on the side of the blaster. Slide or press the switch to the "on" position to activate the light. Make sure your batteries are installed correctly and have sufficient charge for the light to function. Once activated, the light should illuminate, allowing you to aim more easily in low-light conditions.
