Review on 🚦 4-Inch Round Red LED Trailer Tail Light - DOT Approved Stop Brake Turn Lights for Trucks - IP67 Waterproof RV Semi Truck Taillight - 24 Bright LEDs With Colored Lens, Grommet & Plugs Included - 1 Pack by Fernando Ramani

This trailer light replacement is exactly what I was looking for. A simple 3-pin connector made it easy to connect to existing wiring. The LEDs are very bright and I ended up buying another one to replace the other light I had because they are a lot brighter. It is waterproof and the rubber grommet fits snugly in the existing hole. They provide an overview of creating your own hole, which is good for updating applications. I love that it comes with a 5 year guarantee so I don't have to buy more, at least not for that long. Overall, I am very satisfied with my new trailer lights and can only recommend them!
