The SCR lights turn on on after the other and stay on.
The circuit is set to self reset, but if you remove thee relay it will stay on
as long as there is power to the SCRs

Many options available from using a micro controller to using 555 timers and transistors.

With the micro controller you can get way more control over what the LEDs can do. If you wanted to change up the sequence all you would need to do is load in a new sketch rather than changing out the electronics.
