Ok so i got a quick question me & my friends seen this video where the traffic light is set so that the traffic signal changes a light for each lane to go instead of it goes green they all go. To further explain what i'm talking about this video shows what i mean https://youtu.be/mc4-kxjf9Wo?t=122 as you can see the right lane goes green first then red then left lane goes green. how do you set this up?
