So far as I know, all FTO's have the black housing and projector headlights.
If anyone knows differently please correct me but my understanding is there are two types of headlights, projector and reflector.
Projector are those like the FTO has. They are totally clear and basically focus the beam, similar to some expensive torches like a "maglite". The beam typically has a well defined cut-off point.
Reflector are like those seen on most cars. The light passes through a "textured" glass or plastic cover that serves to break the light up and spread the light. The beam, whilst if set correctly does not blind drivers, typically has a blurry edge, or atleast lest well defined in comparison to the projector type.
HID (High Intensity Discharge) does not refer to the headlight assembly itself, it is simply the bulb (and associated hardware).
"Normal" bulbs throw a yellow-ish light, that is what you would be seeing on the high beam and is what most cars have.
You can buy specialised bulbs that throw a "white" light or even attempt to mimic HID colour. The latter of these is usually somewhat successful but the filtering of the light means less light is actually thrown out.
Then there is HID. These throw a very white light or even a bluish/purplish light and are very bright. They typically require a projector headlight assembly as reflector headlights with their blurry edges tend to blind oncoming drivers (there are of course exceptions to this).
So, in closing

, if you had a bluish tinge to your lights before you would have had specialised bulbs or HID's fitted. If you had HID's fitted you would have to also have a ballast which you could look for to confirm this. There would be a box for both lights that the headlight wiring goes into. If there's no ballast, you probably just had normal lights with specialised bulbs in them.
Either way, brand new headlights are gonna be expensive
