Streamlight Railmount HL-X Laser USB: small part, working light
A duty light is a system: the light, its power, and the parts that keep it mounted and running. The Streamlight Railmount HL-X Laser USB is the piece that keeps a ProTac in service instead of in a drawer.
Why it earns its place
- 18650 power. The battery logistics your agency already stocks.
- Tail switch. Controls that work with gloves and stress, not against them.
Who runs it
Officers and quartermasters keeping issued Streamlights in service — the cheapest insurance on gear that has to work at 3 a.m.

About Streamlight
Streamlight started in 1973 and helped invent the rechargeable duty light as a category — five decades later its Stingers and TLRs are what most duty belts and rails carry. 911 Network stocks the Streamlight duty line deep — ask the Network and we’ll match the light to the job.
