We need somebody to commission some 7"bowls designed for LED bulbs.
I can see the enthusiasm for a traditional looking headlamp bowl Dave, but it seems unlikely any manufacturer would entertain such given most sealed LED headlamp units are designed, tested and approved/E marked as an integrated unit, more often than not with accurate projector optics for the dipped beam aspect.
Furthermore there seem to be an increasing range of compliant sealed units, some of which MMC use themselves on the CX range, and prices are reducing. Land Rover units plus the ones that Wolf and KH are now offering come to mind.
