It took a ridiculous amount of brain power to write and debug the code for this animation. I think I have everything in place now, but if there is still a problem, please let me know. The yellow arrow allowed opposing approaches to see a protected/permitted display without having a signal in the median, as opposed to the advance flashing green seen with styles 1 and 2. The biggest difference between this display and one with a median signal is that the arm signal will always have a solid red or green accompanying an arrow, whereas a vertical turn signal will always have an arrow standing alone.
