I stand to be corrected but I am pretty sure that the number on the box is not a match for that headlight. I've looked at my own notes, taken from other lights over the years, and I think this is more likely to be 105.48.65.010.04/10 (Carello #03.483.816), i.e. the outer headlight for a LHD 1750 GTV/Berlina. The lens pattern is non-directional on an inner light.
Maybe someone with an original LHD 1750 can confirm. Hope this is helpful.
Hi Alex, thanks for that info. You're right about the non-directional pattern on the inner lights. It's not a 7" light, so it's not an external light for the 1750 or 2000 GTV, so I think it must be an outer headlight for a LHD Berlina 2000.
