Paul, you say you have some NOS red lenses for sale?? I am looking to have a spare lens (or 2). Would you care to take this offline to email?The only thing that the Ful Vue lights have in common with the aircraft lights is the lens and the bulbs. Most aircraft are 28 volts and the Ful Vue lights used a 14 volt bulb also made by Grimes Aerospace. I have some NOS red lenses for sale.
