Zuomeng Trailer Light Tester Box with 12V 10Ah Battery | IP68 Case & 7-Way Round Pin Compatibility

Overview

The Zuomeng Trailer Light Tester Box is a portable solution designed to simplify on site trailer light checks. Built around a rugged metal 7 pin socket and a weatherproof carrying case, it keeps tools protected and power ready for remote work. A compact, purpose driven device, it blends durability with practical features that matter when you are pace setting maintenance, inspections, or routine checks.

Wireless Remote Control and Convenience

Operate the tester from a distance with the built in wireless remote. This capability reduces the need to shuttle between the vehicle and the tester, helping you coordinate tests with colleagues or work solo without back and forth trips. The result can feel smoother and more efficient during busy inspection days.

Wide Compatibility for Diverse Trailers

Designed to work with common 7 pin round trailer plugs, this tester box minimizes the need for extra adapters. It supports a range of trailers right out of the box, making it a flexible companion for fleet maintenance, campground setups, or DIY trailer projects.

Safe and Self Sufficient

Built in short circuit protection and overload protection help guard the tester and the trailer wiring during tests. The internal power reserve is a 12V 10Ah LiFePO4 battery, so you can test in remote locations without an external power source. The battery provides reliable onboard power for extended use between charges.

Comprehensive Electrical System Testing

Test all trailer lighting functions, including turn signals, brake lights, tail lights, and reverse lights, with clear verification of wiring settings. This helps you assess reliability and identify potential wiring issues before a road test or delivery.

Durability You Can Trust

A sturdy metal 7 pin socket reinforces durability, while the waterproof carrying case is built to resist sun exposure, drops, heat, and shocks. The overall construction is aimed at withstanding harsh work conditions, giving you a dependable tool for field use.
