The "SAE" on a trailer light isn't actually a part number, it stands for Society of Automotive Engineers and just means it has passed certain testing. The only way to determine the correct replacement lens is with the actual part number of the light, though unfortunately those aren't always readily visible. For example, for parts # ST36RB or # ST37RB you would need the Replacement Tail Light Lens for Optronics ST36RB and ST37RB # A39RB.

Without knowing the part number of your light, the only other option we can offer is to replace the light. In order to determine the correct replacement light, you will need to measure your current tail lights and find the one that most closely matches your measurement, and also know if your lights are surface mounted or recessed mounted.

For example, the aforementioned tail lights # ST36RB and # ST37RB are surface-mounted lights that are 7-7/8" long x 3-1/4" tall x 2-7/8" deep. I have added a link below to our entire selection of replacement lenses and trailer lights for you to come back to.
