I am looking for a bulb for my 12 volt 8 inch dia landing light. I have searched for GE 239A19P and for GE 4561 250 watt (Mazda) with no success. Any new options available?
You can buy the 24-volt version but the 12-volt bulbs are “unobtanium” unless the planets are lined up correctly on February 29. There is no modern equivalent. That said, I just spotted one on Etsy for $179 still in the housing that appears to still be for sale. Search “Aircraft GE Mazda Airplane Landing Light”.
