Traffic light script help

[Jefferson Block]

The script I'm using is from cucumberdude's traffic light mod. However, everytime I try to toggle the mod, it keeps saying "You need at least one of each required bricks!" What am I doing wrong here?

Bump, I really need help with this.

there are probably required bricks to go with the script that you need to use the script

ie a green/yellow/red light for it to cycle through
