AirVows Trailer Light Tester Box | 12V Battery, Remote Control, IPX8 Case, 98ft Range

AirVows Trailer Light Tester Box — Versatile, Battery-Powered Diagnostics

The AirVows Trailer Light Tester Box is built for real-world use, whether you’re in a workshop, on-site, or inspecting a trailer during a rain shower. Its compact, rugged design houses a 12V 12Ah battery, ready to power comprehensive lighting tests without constant plugging in. The tester supports multiple connector standards, so you can tackle a wide range of trailers with confidence. Its remote control upgrade adds flexibility, letting you diagnose wiring from a comfortable distance and on your own terms.

Key Compatibility and Testing Capabilities

Designed to work with the most common trailer plug configurations, this tester ships with three distinct detection plugs to cover 7-Way Flat (Spade) Pin, 6-Way Round Pin, and 4/5-Pin Connectors. This broad compatibility makes it a convenient choice for fleets, repair shops, or hobbyists who encounter mixed plug types in the field.

• 7-Way Flat (Spade) Pin
• 6-Way Round Pin
• 4/5-Pin Connectors

Beyond basic compatibility, the unit can verify all critical trailer lighting functions—turn signals, brake lights, tail lights, and reverse lights—and it can check the integrity of the electric braking signals. This helps you quickly assess wiring safety and identify potential faults before a trip or a repair job.

Remote Control Convenience and Safety

The remote control feature is designed for practical use in real-world scenarios. Flip the Local Control switch to Remote Control to begin testing from a distance of up to 98 feet. This enables you to observe lights from the bench, yard, or roadside without needing to constantly reposition the tester. Remember to use your own 23A 12V remote battery, as the remote is shipped without a battery. When you’re done testing, switch back to Local Control to return to manual operation.

Durability, Safety, and Outdoor Readiness

The tester’s IPX8 waterproof housing ensures you don’t have to cancel tests during light rain or damp conditions. Built-in short-circuit and overload protection helps protect the tester and the trailer’s electrical system from common faults while you troubleshoot. The 12V DC battery powers the unit for field reliability, so you can work away from a power outlet with fewer interruptions.
