Jim Peace Posted May 13, 2018 Report Share Posted May 13, 2018 I am not near my parts manual or my airplane. Can someone tell me the lamp size for the gear indication lights as pictured? Is it 327 or something like that? I want to have a couple of spares in the plane. Is there an LED version as well? 1964 M20c Thank you in advance.

The glareshield annunciation bulbs in my plane are 330s. It might be the larger one found in the glareshield (I think GE 1813).

carusoam Posted May 13, 2018 Report Share Posted May 13, 2018 Hey M, Jim probably has the twist iris and push to test, type light fixture... The bulb there is the bullet casing style like David posted further above... Expect the LED version to work well... if too bright, the iris feature should work admirably well. Finding The 12v version is probably the least risk way... How would one identify the 12V version of the GE bullet casing bulb on the Internet?

Jim Peace Posted May 13, 2018 Author Report Share Posted May 13, 2018 Yes they are the push to test and twist to dim type. Thanks all. 1 Quote Link to comment Share on other sites More sharing options...

DXB Posted May 14, 2018 Report Share Posted May 14, 2018 These dimmable 330 equivalent LED bulbs look like a good replacement for both push to test lights and post lights: https://www.ebay.com/i/332633860345?chn=ps&var=541748257913 Just don't advertise to the FAA on any public forums that you are using them in your certified aircraft Quote Link to comment Share on other sites More sharing options...
