'01-'04 Mustang or Cobra headlights are the same. They are considered 'darkened' or 'smoked'. Personally, I'm trying to replace my sun faded/cracked '00 stock OEM headlights with '01-'04 smoked headlights. Much more muscular look, IMHO.
are you basing that on fact or just a glace though a image, you may need to get a close up look, im with you that they are identical but you never really know.... it may just be the bulbs... who knows they are like 15-25 more
my main concern was a possible fitment issue, since the cobra hood and bumper are different I didnt know if the lights may have attached to the alignment panel different or if the panel its self may have been different.
