Protect your flashlight investment with these simple rubber lens covers! This pack comes with two black covers, each with a 30mm diameter - a common size for many popular flashlights and weapon-mounted lights. They're designed to keep dust, dirt, and moisture off your lens when the light isn't in use, preventing scratches and potential light leakage. Made from durable, heat-resistant rubber, they stretch to fit snugly over the bezel. They're compatible with brands like Streamlight TLR-1, Modlite OKW/PLH, and many other tactical or handheld lights. Just make sure to check your light's lens diameter before buying. They're a bit tight to put on at first, but that means they won't fall off. An inexpensive way to keep your gear in top shape.
