This is intended for class 8 trucks, some rv's are just as big and use the same lighting circuits. But this tool is just a test light for 12v multiple circuits, I would just use a 12v test light for a rv if your not sure **Q: Does this fit the larger 7 pin connectors (approximately 1-1/2") or is it for the smaller diameter (approx. 1" diameter) connectors?** A: This is for heavy duty trucks. Most medium and light duty trucks use a 7 pin blade configuration. Also, the approximately 1 inch diameter trailer plugs are 6 pin, not 7. 6 pin plugs do not have an auxiliary power line to the trailer. **Q: You sent me an empty package, I did not receive anythin. what's going on?** A: Call Amazon customer service and support. **Q: Is the stop led supposed to turn green also?** A: On the tester, yes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must for truck drivers *by D***N on January 6, 2025* If you're a truck driver, you need to have one of these. It makes diagnosing lighting issues a snap. ### ⭐⭐⭐⭐⭐ Great tool for a tractor technician *by T***Y on February 25, 2025* A must have in your toolbox or on your truck. I’ve been using this tool daily for over 4 years and it still works great. Has held up over the years without issue. ### ⭐⭐⭐⭐⭐ Great *by K***N on November 15, 2020* Great tool, couldn't go back to not having one. Helps so much to determine if it's a trailer or truck problem. Or if you want to test to see if the cable is bad, plug it into the truck and make sure the power is being sent to the socket, plug the cable back in, and then plug the tester into the other end of the cable. Now it's not good for testing low voltage that can still light up one light on a tester, but for just testing to see if power is making to the trailer it works great. Very convenient. Yes, you could just use a test light, but it's so much easier to plug it in as well as still being able. Plus it gives you a more layman's way to show customers that for example the problem is the truck and not the trailer. ## Frequently Bought Together - Innovative Products of America (7865L) 7-Way Round Pin Tractor Trailer Circuit Chaser™ for Testing Turn Signals, Hazard Lights, Brake Lights and More - GREPSPUD 100pcs Glad Hand Seals Rubber Truck Gladhand Seals Black Polyurethane Seal Washers Grommets Round Gaskets for Semi Trucks Trailers Tractors, Parts Number 10028 - Pigtail Wedge Connector: Secure & Reliable Trailer Light Fix - Eliminates Flickering & Loose Connections for DOT Compliance --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/31277376-innovative-products-of-america-7865l-7-way-round-pin-tractor](https://www.desertcart.vu/products/31277376-innovative-products-of-america-7865l-7-way-round-pin-tractor) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
