technically they could yea
but our lowbeam housings are already a semi projector type
it keeps the same light pattern and spread (tested by myself with a light gun used in MOT in the UK
)
the only thing we are missing is auto-levelers
the highbeams are technically illegal but then again if ur driving around with ur highbeams on u deserve to be shot
lol
i dont think u'd get many complaints from our cars anyway, they are sufficiently low that it wouldnt really bother other drivers
however HIDS in those big 4WD things are like being raped in the face
