Will Optronics Trailer Tail Light # STL42RB Fit a 1974 Blair Horse Trailer

Question:

I was wondering what size hole this light would fit into? Im replacing the tail lights on a 1974 Blair Horse trailer, and the original hole for mounting measures 4 5/8inch in diameter. The original light was about 4 1/2inch in diameter with a larger flange around it. Would these lights fit into a 4 5/8inch mounting hole?

I went out to the warehouse and pulled an Optronics tail light, # STL42RB to measure the back to determine the size hole you would need. The trailer would need, or you would need to cut, a 4-1/2 inch diameter hole. The lights will fit the 4-5/8 inch mounting hole. You would also need a pig tail harness # A45PB.
