I did somewhat the same but differently: for the LED lights on the chest plate, I already had some color changing LED strips so all I did was cut 1 LED out and solder it to a new electrical route and just hid it under a pocket in the chestplate. Now I can interchange it between red and blue and green and purple and so on. ultimately just red and blue is all I need like the film...very cool job on those leds!
also lol, with my own time, i destroyed a gummy-rubberish type animal that had a plastic ball and an LED inside, basically some batteries are connected to the board and whenever the spring shakes, it touches a metal plate and gives power to the LEDs, i found a way to wrap the spring around the red LED so it is constantly on
lol so i can just get some foam, paint it black, superglue it to my mask and it'll be somewhat done
