Description
- 【Useful Features】: This tester detects trailer wiring status to help identify circuit faults. It features intuitive LED indicators: red for tail lights, yellow for left turn/stop, and green for right turn/stop, accurately showing whether circuits are energized. It also functions as a 4-pin adapter for connecting standard 4-pin trailer wiring.
- 【Great Materials】: It uses a durable plastic housing that resists wear and impact. The metal pins have excellent conductivity and stable performance, and is corrosion-resistant and rust-proof, capable of withstanding various usage environments. It also comes with a rubber cap to protect the terminals when not in use.
- 【Plug & Play】: Adopting a plug-and-play design, it requires no additional tools for use. Simply plug the tester into the 4-pin connector at either the vehicle or trailer end, turn on the lights, and check the LED indicators on the tester. If the circuit is functioning properly, all the LED indicators will illuminate.
- 【Widely Used】: Our product is suitable for routine inspections and troubleshooting of trailer lighting systems, applicable in vehicle maintenance, pre-connection checks for trailers, or repair scenarios. It's ideal for auto repair shops yet also convenient for individual car owners to verify wiring status before trips.
- 【Compact Design】: With its small overall size and lightweight construction, it fits easily into toolboxes or vehicle storage. It takes up minimal space during use and is portable, making it an excellent compact diagnostic tool to keep in your vehicle for enhanced daily convenience.
