You can find a variety of replacement pairs at AMAZON. I got a pair of the new sealed led tail/stop/turn lights that had multiple LED's. They replace the ,very dim, LED light that came on my 2017 trailer. the plastic sealed fixtures were about 6" oval shaped- these are fairly standard in length and height i believe. The new ones just fit right into the rubber boot mounted inside the cutouts on the trailer frame. Notice the wire connector configuration. I was able to get an exact match for the plug wire used on my trailer. It was just plug and play for me.
