Tail Light Recommendation to Replace a SAE AIST 04 DOT 2

Question:

I am searching for a tail light for my camper. The first was lost in a hail storm and it appears it is much harder to find a replacement than it should be. I have a 4foot round red tail light with the number SAE AIST 04 DOT 2 on the lense. I have looked at your items and found the set up of PM425-3 to look the same. The lense even looks like the same lense, but mine measures 4. Do you have a book that can match my part to one that you have? Thanks

The Red Trailer Light, Flush Mount # PM425-3 that you referenced would be the correct replacement light for your trailer. This light has a lens diameter of 4 inches.

For further dimensions to compare to your old assembly check out the picture I attached.
