Realize this is old thread but I heard a while back that anything above the headlamp level needed to have a cover such that it could not light and blind.
Off road (non public) use only they may be uncovered. I had 4 KC's beams on overhead light bar covered by solid plastic covers many years ago as well as bumper floods covered and all was good. anything lower than HL and over 55 watts also needs to be covered regardless of placement...but who's gonna check eh? (unless they look like offroad lamps, then they better have cover) exceptions are snow plows etc. or emergency vehicles.
Bottom line is a covered light is nothing more than an aesthetic addition as it's operation is futile; could be fake for arguments sake.
rem- any light not aimed properly can also find you a fine... as driving with high beams on road (they should enforce better).
