Dear Paul,
Do you also consider making flat faced lenses? This would be very popular among airliner modellers for the lights flush to the airframe another example would be F-16 vertical stab lights flush to the airframe on both sides.
AFAIK modern 1/35 AFV has red stop lights which are flat faced too.
Since it is getting harder to find MV lenses and even harder to find flat faced ones, your new line of lenses may become even more popular.
Just a thought.
Yours Sincerely
