The Fenix AER-04 Remote Pressure Switch is a purpose-built accessory for compatible Fenix rail-mounted flashlights, giving you remote control without changing your firing grip. A dual-switch layout combines a textured pressure pad for momentary activation with a raised round button for constant-on, all connected by a flexible PU cable to a robust aluminum tailcap adapter.

This setup is well suited for users who want clean, intuitive light control for hunting, training, or general duty use on long guns. The low-profile pad mounts easily with the included hook-and-loop or cable ties, while the IP68-rated construction and hard-anodized aluminum tail adapter are designed to handle harsh weather and regular field use. It is a practical upgrade for shooters who value Fenix’s consistent build quality and thoughtful design.
