Tree question
 

When did NHRA go from 5 ambers to 3 lights on the tree? Anyone remember what color the bulb indicating who got the handicap was?

Is this a test?

I think it was around the mid 80's? Google check say's 1986.

There is a really good article by Phil Burgess on Dragster Insider about the history of the Christmas Tree. Went from 5 to 3 ambers at the 1986 Winternationals.

In the 1960's NASCAR sanctioned Drag Racing and Atco was one of their main tracks and they used to run the "Leaver's Lose" system.
Two staging lights; one yellow then green very much like a pro tree without all the lights.

I often wonder how such a system might work today? It would probably kill "Box" racing.

It would be great without the boxes
