This project is so amazing.  I just finished a map with about 475 airports.  I'm running the latest version (<a class="navbar-brand" href=" removed link ">v4.503).  I'm using the On/Off timer function.  At the shutoff time the first 400 LEDs turn off but the remaining 75 or so stay lit.  At the ON time everything works as usual.  I'd hate for those last LEDs to burn out prematurely so I'm hoping there's something I can do to turn all of them off at night.  Any suggestions on how to get them all to turn off at night?
