Streamlight TLR Series: Pistol and Rifle Weapon Lights
The TLR-1 is Streamlight’s full-size rail-mounted pistol light, rated by Streamlight at up to 1,000 lumens in the HL version and mounted on standard accessory rails. The TLR-7 is the compact version for pistols with shorter rail sections, and the TLR-8 adds an integrated laser to the same compact format. Match the light to your slide or frame: full-size rail for the TLR-1, compact rail for the TLR-7. Browse every option in our weapon mounted lights category.
Pistol-Specific Mounts and Rail Fit
Micro-compact pistols with very short rails often need a model-specific mount rather than a universal clip. Confirm your pistol’s rail type and the light’s listed fitment on the product page before ordering, and check light mounts and accessories for rail adapters, pressure switches and replacement parts.
Streamlight ProTac Handheld Flashlights
The ProTac line covers handheld tactical flashlights. Streamlight lists models that run on CR123A or AA batteries or a rechargeable pack, with programmable modes on several versions, so decide first how you want to power the light. See the full range in our handheld lights category.
Streamlight for Rifles and Shotguns
Rail-mounted ProTac models bring the same platform to long guns, and remote pressure switches let you operate the light without shifting your grip. Check that the light’s mount fits your handguard (Picatinny or M-LOK) before ordering, and pair it with a rail mount from Light Mounts & Accessories where needed.
Batteries: CR123A, AA and Rechargeable
Streamlight sells lights powered by CR123A lithium cells, AA batteries and USB-rechargeable packs. CR123A cells are widely used in compact weapon lights; AA power is easier to find on the road; rechargeable packs suit lights you use often. Whatever you choose, replace the batteries in a defensive light on a regular schedule and test the light before relying on it.
Streamlight Headlamps
Streamlight also makes hands-free headlamps with white and red output modes for hunting, camping and work. Red light helps preserve night vision. Browse the current selection in Lights.
Streamlight and SureFire
Streamlight and SureFire both make weapon lights used by law enforcement. Compare output, size, switch style and mount fit for your specific firearm rather than choosing on brand alone; both publish specifications on every product page.
