The SAE number you provided is merely an identifier that states that the lamp conforms to certain DOT regulations.

The Glo-Brite 410 has been discontinued and is no longer available. The closest replacement we offer is the Optronics # MCL48AB which is measures 6 x 2-1/4 inches with mounting holes that are 4-13/16 inches apart on center.

I've linked to a product description video for the # MCL48AB lamps.

These measurements do not match my 410 amber lens. Mine is 6 5/8” wide and 1 1/2” high with 6 1/8” holes. Mine are incandescent, would like LEDs

@JohnK Unfortunately, none of the marker lamps we offer are that large. The closest match was the # MCL48AB that I'd recommended. I wish I had better news for you.
