The Optronics Sealed 2-1/2 Inch Round Trailer Clearance, Side Marker Light # MC57AB along with the Round Grommet - Floush Mount # A55GB will require you to cut a 3 inch diameter mounting hole. You will also need the Right Angle 2-Wire Pigtail Plug # A46PB to pair with the female connection on the Optronics light.

I have attached video reviews of these products for you to look at.

The most popular trailer wheel bolt pattern is the 5 on 4-1/2 inch bolt pattern and as far as we are aware the bolt pattern you mentioned is not used on trailers at all. So my bet is you probably have the 5 on 4-1/2 inch. I attached a help article…
