Review on ⚡ SeaSense EZ TROUBLESHOOTER Circuit Tester: Effortlessly Identify Electrical Issues by Nick Walsh

I have a Toyota Highlander and am towing a very small U-Haul trailer. Ordered a wire set online, hooked it up, went to U-Haul and they didn't have these testers so they took me back to the trailer, hooked it up and the light didn't come on. He told me to rent a trailer to keep the lights on. I thought I connected something wrong. Instead of having to go back to the U-Haul place every time I needed to check my wiring was correct, I just ordered this tool and it worked flawlessly! For €4 it was definitely worth it! Now it just sits in my glove box and every time I hitch a trailer I can easily test my headlights to see if my headlights are bad or if the trailer headlights aren't working.
