I have the #29 Mecom, Sebring 1965 Racer model (it's RCR34, right?), purchased in 2010, and it has the blanked out headlights.
If you check the Racer home page;
http://www.racer-emmegi.it/racer.html the listing for the various 250LM models shows an RCR34 version with clear headlights. Click that photo to open up additional pics from different angles, and all of these show a model with blanked out headlights.
Could be that they have run out of bodies with blanked out headlights? Either version is correct as Harry pointed out.
Some of the Racer 250LM models have extra-wide bodies (e.g. the dark blue "Vestey", and the green Piper models). The RCR34 Mecom car has the narrower body which is nicer, I think (it is still a lot wider than it should be for scale fidelity).
Nice car..

Flyslot has done the same model. Very nice too.
