Hi! Here I’m featuring the code to the neon sign’s animation. You’ll need to create TWO overlays - one sign with turned off light (NEON) and one with turned on (NEON2) (make sure they have the same size and placement), then change NEON to you overlay’s name and voila - it’s working! 
If you have any questions, or it’s glitching, feel free to ask me. You can see an example how it works in my IG @adelinaepisode A picture from my story - Space Lovers.
&overlay NEON create and overlay NEON opacity 1
&overlay NEON2 create and overlay NEON2 opacity 1
&overlay NEON shifts to 67 69 in zone 1
&overlay NEON scales to 0.370 0.370
&overlay NEON moves to layer 1
&overlay NEON2 shifts to 67 69 in zone 1
&overlay NEON2 scales to 0.370 0.370
&overlay NEON2 moves to layer 1
&overlay NEON3 create from NEON2 and overlay NEON3 opacity 1
&overlay NEON3 shifts to 67 69 in zone 1
&overlay NEON3 scales to 0.370 0.370
&overlay NEON3 moves to layer 1
&overlay NEON2 opacity 1 in 0.1 THEN overlay NEON3 opacity 1 in 1 THEN overlay NEON3 opacity 0 in 0.1 THEN overlay NEON2 opacity 1 in 0.1 THEN overlay NEON2 opacity 0 in 0.1 THEN overlay NEON2 opacity 1 in 0.1 THEN overlay NEON2 opacity 0 in 0.1 loop INFINITE times
&overlay NEON3 opacity 0 in 0.1 THEN overlay NEON2 opacity 0 in 1 THEN overlay NEON2 opacity 0 in 0.1 THEN overlay NEON2 opacity 1 in 0.1 THEN overlay NEON2 opacity 0 in 0.1 THEN overlay NEON2 opacity 1 in 0.1 THEN overlay NEON2 opacity 0 in 0.1 loop INFINITE times
