They do not come in Bosch boxes so may well be repros, I don't know. Since they look perfect to me when offered for comparison to a NOS complete headlamp I have here and everybody else seems to be delighted with them I have no reason not to offer them at this price.
Colin,
the original LHD lenses have
raised letters and numbers on the front that you can feel with your fingers with the exception of the Bosch logo, that one is raised on the inside and smooth on the front.
The repros are completely smooth on the front. I would prefer well made repros because the last original batches made by the Bosch factory in CR show visible tooling marks and irregularities along the rim and are, imo, inferior.
I assume this also applies to RHD lenses.
