Pistol weapon lights mount to the rail of a handgun and light up a target so the shooter can positively identify it in low light. The category covers rail-mounted handgun lights in full-size, compact, and subcompact sizes. Law enforcement officers, military users, concealed carriers, and home defenders all rely on pistol lights for duty, carry, and home defense.

Options include full-size, compact, and subcompact pistol lights from top brands like Streamlight and SureFire. Models differ in brightness, beam pattern, size, switch type, and rail fit.

Choose the light based on the pistol and how it will be used. A full-size light suits a duty or home defense pistol and is built for maximum illumination, while compact and subcompact lights keep a carry pistol slim and fit smaller frames. The pistol needs an accessory rail, and mounting fit varies by light, such as universal or Picatinny rail mounts. 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. Many lights have ambidextrous switches so either hand can turn the light on. A light changes how the pistol fits a holster, so confirm the holster is made for that light.

Pair a pistol light with a holster cut for it and a pistol red dot for aiming. See more lights for the rest of the setup.
