88 turbo headlights, 6" and 5 and 3 quarter

[pauli]

hi,

got to replace the headlights on my 88 turbo (all 4 lights) i see that lotus performance do these in 6 and 5 and 3 quarter" sizes. I have put a tape measure across my lens on the main/dip and side lens and this seems to be the smaller of the two, but as i am in the u.k i thought these were suppose to be the 6". Maybe i am doing this wrong, does anyone know what the real difference between these two different lights are, apart from the quarter inch. Do they have the same fittings, lensses etc.....


thanks all
