“It’s perfect & very durable for my husband. He is a ruff of tools. So this being in a box is perfect. Easy trailer light tester” - Monique Riley
✅Efficient: Without testing, you could overlook faulty lights or wiring issues. The 7-Way Round Pin Mobile Universal Trailer Tester quickly and accurately checks the electrical and brake systems of trailers.
✅Convenient: The Mobile Universal Trailer Tester is a commercial tool that quickly tests trailer lights and electric brakes by powering each circuit in 7-way round pin arrangements. It verifies wiring, checks ground integrity, identifies short circuits and overloads, and simulates turn signals and brake operation.
✅High Quality: The Trailer Tester has a rugged, water-resistant design with an internal battery compartment and an external 12V power port for memory saving, test light supply, or trickle charging. It includes a 500mA battery charger.
Q: Can you adapt it down to test 4-pin, 6-pin, or 7-pin flat-style trailers?
A: No unless you get adapters.
Q: When charging, why will the light flash red and green?
A: That indicates when charged or not charged. Red means it's charging and green means fully charged.
