As long as they're easily paintable without days of sanding to hide the weave, who cares.
Tom, a few questions as things are now all but settled by the sound of it. Will the complete units be a 3-part (lens, visible trim piece and back/cover) construction, like the originals? Is the HID unit a bi-xenon type unit with high and low beam? And/or is the high beam handled by a separate halogen reflector lamp like the OEM lights? Has the halogen lamp changed size to allow space for the new larger HID lamp?
HID unit is bixenon.
High beam will also have the same Hella branded halogen unit to retain flash.
Halogen lamp is the same size, modifications to accomodate the larger projector are limited to widening the projector opening.
Construction is front lens and visible trim. Back is likely to be vacuum molded similar to original, however I'm experimenting with individual projector covers (similar to halogen spotlight socks). Key enabler for this retaining this construction is the improved projector mounting arrangement - bighead composite fasteners.
Answered my own question again.
