Hello Ben, thanks for reaching out. I went out to our warehouse and measured the Optronics LED Trailer Marker Light # OPT37KB. The mounting holes are 2" apart on center. The same is true for the red version part # OPT77KB.
Reply below with any other questions or comments and I will get back to you.
