Is 440-15R The Correct Replacement Lens for Monarch 5124 Tail Light

Question:

I am in need of replacing 4 lens on my motorcycle trailer. It has the old Monarch 5124 tail lights which use a 9074 lens. Will this lens fit my old tail lights? I would replace the whole assembly, but it is a fiberglass trailer and do not want the holes to be different. If this one does not fit, do you have one that will? Thanks

I wasn't able to find any dimensions for the Monarch 9074 lens online, so I can't say for certain that the part #
440-154 lens would be the connect replacement but I'd be happy to provide the dimensions of the lens, and you can compare that to one of the remaining lenses to see if the screw holes that attach the lens to the lamp housing are correctly spaced that that the height and width of the lenses are compatible.

You can see this info in the provided photo. If your existing lenses are 4-5/8 inches square with a 3-3/4 inch on center distance between the screw holes, the # 440-15R would be a great replacement for your motorcycle trailer.
