.400 pro tree help

-
I suppose if the lights are wired sequenchially there may be a Nanosecond delay that might be seen in superslowmo...
 
we raced on a Pro tree for many years in Div 7 bracket classes....Super Pro and Pro both ran the Pro Tree....instead of looking at the whole tree...i concentrated on one bulb ...the one with the shortest wiring...
 
It says all 3 Amber lights flash simultaneously, then the the green lights up, .400 sec after that. Now a days, .370 later. I'll see once racing season starts in a couple months. Pretty sure all ambers light up, then the green .370 sec later . Slow mo prob shows a fast sequence top to bottom on the ambers.

Actually not true. Supposed to be that way, but if you watch a slow mo video of the tree you will see that the lights progress from top to bottom. I find that if my lights are slow I stare at the top bulb. If they are to close I move down the tree to the bottom bulb.
With the old incandescent bulbs this statement may have some validity, but with modern LED's there is not a perceptual difference between the 3 bulbs firing.
 
This is not something I heard, all I run is a pro tree. I have seen it on video and have made adjustments to my reaction times by changing which bulb I look at. I understand that led bulbs "light" much faster which would reduce the lag time, but honestly I don't think the tracks I run at have LED Amber bulbs. Not national events Atco/Cecil county/New England/Lebanon Valley/Englshtown/Island ect. It also comes down to how the tree is wired and how the controller works. Each track is a little different. I run at 4-5 tracks a year and qualify three times, if my reaction times are really to close for comfort I focus on the bottom bulb. I have noticed my RT were crap during qualifying and catch myself looking at the bottom bulb.
 
What does this mean
