Nice quality and works well. I have four trailers and had my share of ground issues, brittle wiring and bulb issues. I should have had this years ago. It quick and easy to use.

Very nice gizmo to check to see if your trailer light connections are indeed working. It showed that mine were working. Great price and great product.

Does exactly what I wanted it for. I knew my car wiring was okay and that it was the trailer lights that were the issue.

J'avais un trouble électrique sur ma remorque et ça m'a aider à le solutionner. J'ai du faire plein de test avec des combinaison d'éclairage pour comprendre ce module. Des instructions seraient appréciées.
