Runway alignment indicator lights are also known as RAILS. The horizontal beam pattern and bright simultaneous flashes helps the pilot identify the runway in use. ![]() These lights offset the need for circling and provide clear visuals for non-precision landings. These are high-intensity white lights, steady or blinking. These are the first lights a pilot will see as they approach the airport. 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. Omnidirectional sequenced flashing lights may feature a configuration of seven lights on the runway. Approach lighting Runways have additional lighting on the approach, often extending beyond the airport perimeter. Aerodrome Lighting Approach Lighting Systems Non- Precision Instrument Runway- Simple approach lighting system 5.3.4. ALS are a configuration of signal lights starting at the landing threshold and extending into the approach area a distance of 2400-3000 feet for precision instrument runways and 1400-1500 feet for nonprecision instrument runways. Your motor and reed switch method will work, but it will not be as reliable as the electronic version and the motor will chew up batteries and spit them out compared to the electronic type. If you intend to substitute the LEDs with others more suited to your runway lights, let me know and I can search my catalogues for suitable parts for you. The sequential flasher on the Goldmine site is the same thing, so I recommend you use it to avoid making a circuit board and hunting around for the other parts. 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. ![]()
