Review on 🚦 Blazer C7425 LED Square Trailer Light Kit with Integrated Back-Up Lights, 20-inch by Dave Hock

I had to make modifications to fit the headlights to my trailer. I completely enclosed the light mounts and the license plate light was wider than the cutout. Other than that they are perfect. Lots of brightness and these are the first LED taillights I've had that didn't have to use a pull up resistor to work with my Audi. Many new cars use PWM to check for blown bulbs so the car knows if a trailer is connected to it. They will work with a standard 7 pin to 5 pin adapter.
