I used the VHT Nightshades for my tail lights.. after I was done thouhgt I went too far. Luckily I have an 07 with the bulbous tail lights, so I took some 220 grit and sanded the centers back some and hit the lenses with two coats of clear. Now they are perfect, they look absolutely darked out, but the center round sections of the 07 tail lights let light out perfectly.. now to finish up the rest of the markers and such!
