We seem to be going thru landing lights more frequently than we should in
our 172's. Are there any STCd alternatives to the standard Cessna part?
Maybe a LED lamp or at least something more durable? I realize it's only a
$40 part, but we're a new club and every little bit helps...

A few suggestions.

1. Make sure that pilots are not turning the lights on/off/on in a
short timespan. I have accidentally toggled the light switch on my
Cherokee, and it blew the light very quickly.

2. I orientate my bulbs so that the filament is vertical. This is
supposed to help with the vibration issue, but who knows.

3. If you have wingtip lights and nose bowl lights, use only the
wingtip lights when possible. There is less vibration in the wingtips
than in the nose bowl.
