Doesn't bother me but, I have a little cheap Mobius camera that I use as a dash cam. In the initial set-up you can set it for American or European (indoor?) lighting -Defeats the frequency issue...would think it should be an easy fix.
If you watch an airliner takeoff/landing video on YouTube, one with a glass panel, the monitors often do the same thing - blink like crazy. Not sure exactly what phenomenon causes it. Obviously the stage bulbs at Epping were working just fine.
Bob, are you kidding me!!!!!!!!!!!! THe stage lights have like that for over a year and I'm sure you could have contact someone at NHRA rather than expecting Alan to do it and I'd bet money they were aware of it long before this race.
Agreed Alan, It's the frequency of the LEDs' V.S. the Shutter speed with the cameras. They finally got the frame rate squared away with the incandescent bulbs then upgraded the camera and leds'. Back to square one. A little known fact, Everyone that had a newer car with "HID" lighting on their car, which most have, it is in fact a glorified strobe light that flashes faster than your eye can see. "HID' high Intensity Discharge" Light.
