Hi mate and welcom

I have a topic on fitting the projectors to the mk2.5 ( facelift ) focus but that's not complete yet, but I do have a bit of knowledge on the subject.
The simple answer is no the bulbs will be different. Projectors use bulbs wired for use with a ballast, these are know as 'xenon' bulbs obvs where tha name comes from
These are D1s D2s D3s and D4s and each fit projectors differently, however a D1s bulb and D3s will fit one socket and D2s and D4s will fit another. These must be run from the correct ballasts due to the different elements in the bulbs.
That basically means the D1 and D2 bulbs contain mercury and are not 'environmentally friendly' the D3 and D4 contain no mercury and are much newer. Hence why they need different ballast so a D1 bulb will fit a D3 projector but will not be safe to run from the D3 ballast.
Hope this clears up your problem, any more questions just ask
