Just to make clear what the photographers flashes may create, I've seen this happen in a number of Comp Elim races, where a camera flash bounces off the second off the line handi-cap racers front wheel and makes the racer's light turn Red, WITH-OUT the racer's car moving.
It's even been suggested some racers have their photographer or paid a photographer to take these flash pictures, so their competitor red lights.
I've seen a crew member's videos, showing the tree and the complete race car, and I've seen both stage lights on, and the racer getting a red light with-out any movement of the rear wheel. What happens is a photographer takes a flash picture of the 1'st car leaving on a handi-cap race and the flash reflects off the 2'nd racers front wheel and triggers the red light. that's what happened at the Winternationals SuperStock final, and they re-ran the race after telling all the photographers to not take any flash pictures during the tree count down.
As a result of this happening, many racers are making their front wheels black. I make and sell front dragster wire spoke wheels and many racers are getting my black rim wheels.
