Just an FYI, those round rubber mounted trailer lights found at most parts stores, truck stops, and trailer supply places like Tractor Supply will fit the holes below the factory hard plastic lens and reflector assembly. Super easy to re wire and I went with a 6 light LED version. After removing the stock assembly, just insert the rubber ring and wire as necessary, plug in and pop the light assembly into the ring. It will seem to be too loose, until it is all together. I believe they are better weather resistant than stock also.
I already have lights mounted for backup lights and the ones I changed are the tail/brake. They are floating in the rubber ring. No screws to hold them. Super easy to pop out and back in to access anything behind thwm. They fit semi trailer and container chassis. Just an inexpensive alternative available at local stores. I'm going to try the smaller ones for the turn signals front and rear.
I did the rear turn signals too with 2 1/2 inch red LEDs. Rubber ring mounted and easily replaced if needed and more water resistant than the stock light. When I took the stock lights apart, I was shocked to find the ground wire soldered to the spring for the light. Wasn't soldered solid either, it was slipping on the spring, so not the best connection. I did have to enlarge the hole for the rubber ring to fit though. Not hard with a jigsaw.
