Actually, the transparent suit is the 1st stage of the "Eradicator/K" healing suit which protects Superman's wounded body.
As you can see on the picture above, the "resurrective suit" was meant to show the inside of Superman's body and make the musculations & tendons look very robotic. I guess they kept the basic idea of a transparent suit but they tried to come up with different textures for the inside of the suit.
And then the suit would have gone into its 2nd stage with a black liquid covering it and turning solid, giving birth to this:
Now, about the whole L.E.D. covered suit. In Dan Gilroy's latest version of the screenplay (dated 20 Spetember 1998, which is the last draft written with Tim Burton still attached to direct), when Superman busts out of his tomb in the "K" ressurective suit, he tries to take on a bunch of thugs trying to rape a woman, but he quickly realizes that he's now powerless. Suddenly, a green light runs through the contours of his muscles, and Superman regains something like a tenth of his actual powers. So that's what the whole light test thing is all about and I guess they were trying different colours of light, different patterns, etc.
Hope this shines some light on the nature of these images and what Tim Burton was trying to do with his Superman film. But for those of you who are still wondering, the answer is no, none of the suits above is the "classic" Superman suit that the Man of Steel would have worn at the beginning of the film.
