This is a beautiful "stealth mode" new face.
While the welding spots is the problem, I agree with gbeer about plugs, hey, if the welding spots could make perfect circles, that'll be also acceptable.
It is possible to hack these buttons and the knob using fiberoptic wire, but it would be a lot better to have translucent buttons for this mode. I cannot make out from the pictures whether Firefox's translucent knob will go there, but this aluminum knob sure looks impressive. Is it possible to have ridges on the side of the knob?
