Pit Viper Lights provides pole mounts with every pit light set we manufacture. The provided pole mounts need a surface area at minimum of 2-1/2” wide by 3-1/2” long to be screwed into your enclosed trailer or open trailer. You may need to modify your pole mounts to work with your particular trailer, but we do provide self tapping screws. We simply cannot provide every possible mounting solution for every type of application. We hope you understand that we offer one solution that will work in most cases.
