You serious? The housing is a clear plastic yes? Inside the plastic to the left hand side is a yellow indicator to the immediate right is a patch of black (that is the colour of the inside of the light - Black), the next you see is indeed chrome, that is the surround to the headlight bulb, this is chrome on every single light whether it be the black inside, silver inside, mk2 or mk2.5, the same for the sidelight etc. If you have a 'black' light NOT like this one, then I suspect you either have a custom home made job, or some aftermarket light.
this is the bit that looks chrome to me .i know about the rest.
just got car back from repiarers ,and once again they have put a chrome inner headlight on instead of black.i did warn them not to.they recon they cant get a black style one ,ive seen them about.but they recon they have been superseeded by the chrome ones.do fords still sell the black ones
