Maplight replacement

[M20F]

Is there any LED bulb that just drops into the map/panel flood lights?

In order to have LED lights, you need a PWM to dim them.  You can find them on the market or your hanger fairy might be able to prototype it.  Of course, rarely do hanger fairy do TSO work though.   The existing rheostat won't do the trick.  

Check this out though....  http://www.aircraftspruce.com/catalog/elpages/fiberlite.php

I am going to do this in my plane at the annual.  Really cool stuff.
