As far as dark headlights go, if you've got a 2000-04 Focus you could look into a set of ST170 headlights (european headlights with dark gray housings, integrated signal lights and superior lighting), or even a set of the cheapo ebay projector headlights with the black housings.

Also for tinting taillights, be aware that some insurance companies may deny coverage if they say that illegal modifications contributed to an accident. Ie. it's a sunny day and you brake and get rear ended because the guy behind you couldnt see your lights come on.. Just something to be aware of.
