Review on Partsam Magnetic LED Trailer Towing Light Kit with Reflex, Universal 2X 15 LED Trailer Rear Light, Board Tail Brake Stop Indicator License Plate Light Lamp, 24ft Cable with 7 Pin Plug, IP68 Waterproof, Enhanced SEO by Rud Starks

It seems the only way to keep the connector in our trucks' 7-pin connector is to use tape. Since we haven't had this problem with anything else we've hooked up to a truck in the last 7+ years, we're assuming it's this product. I'm still trying to locate the brake lights, when we step on the brakes the yellow gets lighter than the red. Hm. And I'm wondering where the license plate light is coming from. That works well enough. The price is reasonable and it's a lot easier than converting a trailer.
