Proper storage : Store the flashlight in a cool, drs place away from direct sunlight and extreme temperatures. This helps prevent corrosion and damage to the plastic or metal components.

Lubrication : Apply a small amount of silicone lubricant to the threads and O-rings (if present) to keep them moving smoothly and maintain a waterproof seal.
