My question is, how do I make 2 red flashing LEDs flash synchronously? The flashing circuitry is within the LED, and I guess that they will have noticeable differences if they run for a little bit. Is there something that I can put before non-blinking LEDs that can have multiple LEDs connected and will have them blink synchronously? I would like to use this in an upgrade to my 6517 caboose (the taillights), and if I can get that to work, I may put it in as taillights in my 68 executive inspection car.
