What works for me is to find some round lights and then some pipe that's larger in diameter than the lights. Weld the pipe to the frame, weld a flat strip of metal across the front with the hols drilled in it to mount the lights, and then drill some holes in the side (if you worried about side marker lights) and bottom (if you're going to mount the plate below the taillight). They sell a nice 2 1/2" taillight for motorcycles that are pretty cheap. They have one mounting stud in the back so they are easy to mount inside the pipe. They are a little small so I would put two or even three per side.
I've always used 4" diameter lights but then now seam to all use the rubber gasket around the outside which makes it hard to recess them inside the pipe (but it could be done. I've never done it but you could weld a ring inside the pipe, slide the light into the pipe with the rubber gasket in, and then another ring of steel to sandwich it. That second ring could have expanded metal on it to protect the light.
I also like to weld stainless bolts to the frame for ground points. You'll never have ground issues.
