The Whelen L31HAF is a low-profile, 4-inch-tall amber Super-LED® beacon designed to provide powerful 360-degree warning coverage. Within the L31/L32 family, the L31 uses the high-dome configuration, while maintaining a shorter overall profile than many conventional warning beacons.
This 12 VDC, single-color model uses a permanent flat-mount base and provides 69 Scan-Lock™ flash patterns, including four simulated rotating patterns. Dynamic Variable Intensity™ technology, high/low intensity control, cruise-light operation, and Sync capability provide flexible warning performance for different operating conditions.
The L31HAF features a smooth, hard-coated polycarbonate dome, powder-coated cast-aluminum base, conformal-coated electronics, reverse-polarity protection, and minimal RFI/EMI radiation. Its rugged construction is designed for long service life in harsh weather and heavy-duty fleet environments.

| Mounting | Secure to a flat surface in the normal dome-up orientation |
| Pipe Mounting | Use optional L360PMKT for 1-inch NPT pipe mounting |
| Circuit Protection | Use a 5-amp fuse for the standard 12 VDC circuit |
| Wiring | Use properly sized wiring; waterproof exposed connections and protect pass-throughs with a grommet |
| California Compliance | Select L31HAFCA when California Title 13 compliance is required |
| Visibility | Position the beacon so its warning output is not obstructed |
| Cleaning | Clean with soap and water; do not use a pressure washer |
