If you choose to use incandescent lamps in the garage door opener,
choose the "heavy duty vibration resistant" bulbs. These can also be
found labeled as "ceiling fan" bulbs. Seems that they have 3 or 4 wires
supporting the filament as opposed to only two wires for the standard bulb.

Thanks, Bill. I have the newer DC motor with Battery Backup Liftmaster, but I’m
guessing the receivers might be similar. Interestingly, in the new manual they
actually recommend CFLs but warn against LED. Obviously the front end of their
receiver is not designed to Elecraft standards ;>)
