Night Fision tritium night sights for Glock deliver a low-light aiming solution that doesn't depend on batteries, light reflection, or daylight. These sights are built around self-illuminating tritium vials that glow continuously in darkness, making them a reliable choice for home defense, low-light hunting, or any shooter who wants fast, confident sight alignment when the sun isn't cooperating. The GLK003003OGZ model pairs a green tritium front sight with an orange outline against a green tritium rear sight with a black outline—a contrast-rich setup designed to help your eye find and track the front sight quickly.
Installation on your Glock is straightforward if you have the right tools; these sights use the same dovetail slots as factory Glock sights, so they're a drop-in replacement on compatible models. Once installed, you'll notice the sights glow steadily in darkness without any activation or adjustment needed. The tritium will remain visible for years—though brightness does dim over time, as is normal for tritium products.
Night Fision night sights appeal to defensive shooters, hunters who work low-light hours, and anyone who keeps a Glock for home security and wants to eliminate guesswork in a dark room. They're also popular among competitive shooters who train in various light conditions and want consistent sight acquisition. If you're buying night sights for the first time, understand that tritium glows, not illuminates like a laser—you'll see a steady glow rather than a bright beam, which is exactly what makes them reliable in complete darkness.

No. Tritium is a self-illuminating radioactive isotope sealed safely inside the sight vials. It glows continuously without any battery, charging, or external power source—a feature that makes tritium sights reliable for defensive carry and emergency use when you can't predict power availability.
Tritium glows steadily in darkness but is invisible or nearly invisible in bright daylight because the daylight overwhelms its output. That's why Night Fision includes the orange and black outlines on these sights—they give you a conventional aiming point in daylight and the tritium takes over when light fades.
Tritium brightness decays predictably over time due to its radioactive half-life. These sights will glow noticeably for many years, though brightness gradually diminishes. The exact timeline depends on storage conditions and use, but tritium night sights remain a popular long-term investment for shooters who want reliable low-light capability.
