Help in identifying lights

I need two new rear lights and bulb holder/plugs for my Big Deck. I can't imagine that the lights would be specific to it and that it would just be standard pickup lights but I don't have one to compare. Could someone please look at this photo and help me confirm as to whether these are just standard Pickup lights? Many thanks
