Have a look at the
VF/WN/HSV workshop manual found within this forum and you’ll see that there are wiring differences, a HID headlight and lamp control box and likely BMC specific program settings to make it all work. The later likely being the biggest issue.
(Interestingly the manual also talks of headlamps that turn left and right to follow the steering...)
And if you look at the Caprice HID headlight design (shape) you’ll realise it won’t fit in VF.
But all is not lost as the Chevy SS had factory HIDs so they should be able to be simple retrofit though the likely BMC programing issue still exist. The other problem for us with using Chevy HID headlamps in our VFs is that they don’t come with washers as they are not required in the USA.
(and it’s a dumbass cheap design to not include the washers with the Chevy SS as it make it more expensive to then provide the feature to other VF’s but Holden/GM were never ones for vision; just look at LHD only designed Camaro and at Ford making Mustang hay while the sun shines)...
So it’s possible to Frankenstein’s the Chevy SS HIDs, wiring, control box, etc and maybe even modify the Caprice HID washer system to pop out from the bumper but it will be rather costly... and then the BMC may be a hurdle to get programmed (service department balks when asking about such programing as they have no idea).
It’s possible but thing in the many $grands rather than the many $hundreds... and then it will need engineering. but you’ll get HIDs with levellers and washers and not blind oncoming traffic
