Is there such thing? If not, can I get a parabolic reflector made for my headlight?

they are most easily found in other headlights.
alternatively, you could make a parabolic mold, then bend some material to fit (you wouldn't want it to be heat affectable tho), then get it plastic/chrome plated..
other headlights would be far easier.

Its your regular headlight reflector but it has a whole lot of prisms all over it. So it reflects the light differently. SO instead of being flat it has shapes all over it. New expensive cars tend to have them.

a reflector will not change the colour. you just bought the wrong temperature range HID if you want the blue/purple look...
and a parabolic reflector (not a sheet) is either a siple parabola, or a multi faceted lens that replicates a parabola in a slightly smaller space, without a parabola's tight focus. a bit more dispersed.

i didn't say it would be easy... calculating all the angles and the beam spread i think would be beyond most people.
so you just have the HID's (minus one casing) and you are making reflectors???
why not just use a whole unit from a different car and stop buggerising around
