Rifle weapon lights mount to the handguard of a rifle or carbine and light up a target so the shooter can positively identify it in low light. The category covers weapon lights for rifles, carbines, and other long guns that mount to a Picatinny rail or M-LOK handguard. Military users, law enforcement officers, and home defenders all rely on rifle lights for duty and home defense.

Options include compact long gun lights, high-output lights, and lights sold as kits with remote switches and mounts from top brands like Streamlight and SureFire. Models differ in brightness, beam pattern, size, battery type, switch type, and mounting.

Choose the light based on how the rifle is used. Check how the handguard mounts accessories, since some lights clamp to a Picatinny rail and others use M-LOK, and kits often include the mounts and a remote switch. A remote pressure switch lets the shooter turn the light on with the support hand without moving off the grip, so mount the switch where the hand falls naturally. Brightness is listed in lumens, which measure total output, and beam intensity in candela, which measures how far the beam reaches: a tightly focused beam helps identify a target at a distance, and a wider beam lights up a room at close range. Some lights run on more than one battery type or recharge by USB, which keeps the light ready without carrying extra batteries. Compact lights add less bulk to a short carbine.

Pair a rifle light with a rifle red dot and a sling for the same setup. See more lights, including pistol lights, for the rest of the setup.
