- To turn the light ON, push the switch forward (away from the handle).
- To turn the light OFF, pull the switch backward (towards the handle).
5.2 Locking Slide Feature
The light includes a locking slide feature to prevent accidental activation, which is crucial for preserving battery life and avoiding unintended light exposure.
- To LOCK the switch, slide the small locking mechanism (usually a small lever or button near the main switch) into the locked position.
- To UNLOCK the switch, slide the locking mechanism back to the unlocked position.
5.3 Pistol Grip/Lantern Handle
The versatile pistol grip/lantern handle can be quickly converted to multiple positions for flexibility in use and carrying.

6. Maintenance
Proper maintenance ensures the longevity and reliable performance of your Pelican 4100N Dive Light.
- After Each Dive: Rinse the light thoroughly with fresh water to remove salt, sand, and other debris. Operate the switch several times while rinsing to flush out any trapped particles.
- O-Ring Care: Periodically inspect the O-rings on the rear cap and front bezel for cracks, nicks, or dirt. Clean them with a soft cloth and apply a thin layer of silicone grease to maintain a watertight seal. Replace damaged O-rings immediately.
- Battery Compartment: Keep the battery compartment clean and dry. If batteries leak, clean the compartment thoroughly and dispose of the old batteries properly.
- Storage: Store the light in a cool, dry place away from direct sunlight. Remove batteries if storing for an extended period to prevent corrosion from leakage.
- Lens Care: Clean the polycarbonate lens with a soft, damp cloth. Avoid abrasive cleaners or materials that could scratch the lens.
