This is the USB rechargeable package of the compact "Pro" model in Streamlight's 2026 ProTac Rail Mount 1L-X series. It's a multi-fuel tactical weapon-mounted light optimized for short-barreled rifles (SBRs), AR pistols, carbines, and submachine guns with limited rail space. The "Pro" designation and included Jack-Cap® tail cap provide operational redundancy (push-button or remote pressure switch), while the USB version ships with the SL-B9 rechargeable battery pack and charging cable for convenience.

The 89025 stands out as the full "Pro USB" kit: it combines the Jack-Cap redundancy of the 89024 with the included SL-B9 rechargeable battery of the USB variants. Compared to the non-Pro USB (89027, standard tail switch) or base models, it offers maximum flexibility for users who want both push-button simplicity and remote switch capability right out of the box. Early user and reviewer feedback highlights its bright, focused beam, compact fit on short rails, multi-fuel reliability, and durable construction.

- Owners of SBRs, AR pistols, or compact carbines needing a low-profile light + pressure switch setup.
- Tactical users wanting rechargeable convenience with CR123A backup for long-term storage.
- Anyone prioritizing switch redundancy on a compact weapon light.
