Errr.. wouldn't the leds at 0:23 cause an accident?

(I know, im overly serious.)

[SheldonMaloff]

@will4210 Shouldn't. Green for the Westbound lane, green for the Eastbound lane. :-) If it was a really busy intersection, then I might let only one lane go green at a time.

How did you make thise light up?

[scottclements78]

@SheldonMaloff It shouldnt matter when traffic is going straight. When someone wants to turn across the intersection into the side street it will cause traffic to build up if its busy the opposite way. In that case then you would only want one green at a time.
