LINGYAO 5-Pack Backup Alarm 12V-48V 107dB Universal 2-Wire Reverse Beeper

• 110dB Super-Loud Pulsed Tone, 12V-48V Auto-Range​ Emits 110dB ±3dB at 1 m​ pulsed "beep-beep" that cuts through diesel idle and yard noise. Internal regulator auto-ranges to 12V/24V/36V/48V DC​ — one SKU covers light vans, box trucks, and 48V industrial equipment. Draws 0.1-0.6A depending on voltage; no jumper, no relay.
• IP67 Epoxy-Potted, Self-Grounding Steel Plate​ Nylon+ABS shell with epoxy-encapsulated PCB​ rated IP67​ for rain, pressure wash, dust, -40°F to 185°F. Mounts via self-grounding steel plate to any metal chassis — no separate ground wire needed on steel bodies. 3-bolt 3.25" or single-plate mount.
• Universal Heavy-Duty Vehicle Fit​ Direct 2-wire hookup (red = reverse-positive, black = chassis ground) to reverse lamp or reverse switch. Fits trucks, vans, freight/lorry, box trucks, RVs, forklifts, skid steers, excavators, ag loaders, go-karts, and yard tractors​ on 12-48V reverse circuits.
• SAE J994 Type A / 735-Pattern Replacement​ Crosses the common industrial 735-pattern alarm and Farbin/Mirkoo/Kerwinn 12-48V beepers. Not a 12-80V unit — state clearly for fleet buyers running 48V electric yard trucks. Fixes silent-reverse citations and OSHA-style backing-awareness gaps.
• 10-Minute Bench Install, 5 Units in Box​ Splice red to reverse hot, ground black under a frame bolt, bolt alarm to bumper/step/chassis. No programming. Bulk 5-pack for fleet/workshop replenishment — test tone before final tighten; includes butt connectors + self-tappers.
