The motor type will also be bulkier, plus you have to putz with modifying the radio servo and mounting the reed switches, so for all those reasons, if it were my project I'd go with the electronics. Runway guard lights, VFR/runway hold line & white/red mandatory sign. Taxi and runway turn-off lights are used at the captain’s discretion while taxiing.

A Flashing Red light signal on the ground means the same to an airplane as flashing red lights mean to a car. The old PE mags I have show a couple of solid state projects for doing what you want, but the articles are at least 20 years old so that means the PC board would not be available from the listed source, although the parts are all still common.
