How to stop traffic on 2499 on a dime ... legally!

Talk about power! My son and I were riding bikes, and we had to cross 2499. The safest intersection on the south side of town is the little traffic light at Aberdeen (south of 3040, north of Spinks). Today I learned that when you push the button to let the signal know you're there ... it immediately drops a yellow light on the speedway traffic zooming by. (Sorry folks!) It worked on both sides of the road.

Until they make it legal for me to possess one of those emergency traffic-signal switching devices that fire trucks and ambulances carry ... this may be the next best thing.
