Truck-Lite 92916 Commercial 4" Round Back-Up Alarm | 97dB, PL-3 Connection, Flush Grommet Mount, 12V

Standard 4-Inch Flush Mount Design: Specially designed to fit seamlessly into industry-standard 4" round lighting cutouts using a standard rubber grommet. The flush-mounted configuration stays recessed to avoid impact damage from loading docks, road debris, and low branches.

Steam-Cleanable Construction: Safely tolerates high-pressure commercial pressure washing and chemical decontamination, ensuring that moisture never degrades internal electronics.

Plug-and-Play PL-3 Interfacing: Arrives pre-configured with a universal 3-pin PL-3 connection socket on the back, allowing it to instantly hook into existing industry-standard electrical pigtails without tedious wiring work.

12V Fleet-Optimized Circuitry: Fine-tuned to operate at peak efficiency on standard 12-Volt DC electrical systems, drawing a minimal 0.2 Amps while delivering maximum acoustic warning power.
