I have a 1975 M20F and will be opening the belly (with an A&P) to inspect/service the switch that indicates the gear position. When I'm down there, I want to replace the bulb that illuminates the background of the gear indicator window in the floor. I want to be ready, so I need to know the bulb specs in order to not lose any flying time. Also, is there an LED substitute so I won't have to replace it again in the near future?
Thanks again for your help,
Larry
