There's absolutely no way an ls430 will fit. The wide beam is a characteristic of the rx330 projectors though too, just not as wide as ls430. If you fully mod rx's with a custom curved shield you get some crazy width and intensity along the sides. The projectors in the lights above only have a clear lens mod not the shield mod. Go over to hidplanet if you want to learn more on the shield mods. You can even make the rx's bixenon...
