I have smoked heads and fogs from AM. The housing is smoked, while the lens is clear. Thus, you won't "lose" any light.
To install or replace headlights on an 05-09 you must remove the front bumper cover, not a hard task, just put aside about 2-3 hours. For fog lights, simply remove the upper grille and unscrew the fog light brackets from the grille, then swap the fog housings and screw them back into the grille.
Smoked CCFL halo headlights were $185 and smoked CCFL halo fog lights were $125 for me. Idk about smoked OEM-styled ones, probably cheaper.
