Almost landing gear Indicator LEDs - Simulator

00:41:59

Trying to set up a push button to turn on red for 7 seconds then goes out and green comes on. Push again and green goes out and red is on for seven seconds, then both are out.  Crashes unless separated.

555's like at least 150 Ohms on the output pin or the can crash, because of that a transistor to drive the first output relay would help. The circuit you display has far too many extra components in it for the purpose you describe, look at my circuit again and work from that. http://everycircuit.com/circuit/5383899107295232

Yours is good but I need the latching part of the circuit. But, I do think your circuit could be a much better base. I am going to see what I can come up with this weekend, thank you
