ATF: Bighorn - Missing lens cover door side flood/scare light

On drive from Louisiana to Texas via I-10 I noticed lens cover popped out. Is it possible to get just the lens itself or do I have to replace the whole fixture?

I had rusted frames on my Scare Lights and did some research. Found them with Stainless steel Rims at etrailer.com. Very inexpensive, Same lights used in Cargo trailers on big truck trailers. Same light! I dont recall but i think 2 were less than 15.oo.
