Hello Alan, thanks for reaching out. The Peterson LumenX LED Trailer Tail Light # M824R-7 may work for you, but we will want to be sure it is dimensionally identical to your current lights. The light itself is 4-1/4" in diameter, with the flange being 5-1/2" in diameter overall. Then the mounting holes are 4-1/4" apart. Please compare this to your current light and make sure it is a match. If you need a different size light just reply below and let me know.
