the 55.5-59 panels all have the 'outer' 2 oval tail lights, the 55.5-56 also have a light on the drivers side rear door like the one on the 47-55 lights - so not "2 styles" in terms of one or the other, but the 55 and 56 have both ... in 57 the door light was changed to a simple license light
there are lenses and lense gaskets available for both types, but no bodies or bezels, and no parts at all for the 57-59 license light
