Re: pre-stage-stage lights flashing
Alan Reinhart explained on NHRA.TV that the staging lights used at the four-wide tracks (even when running just two lanes) emit light at a different frequency than the others on the tour.
The digital cameras they use sync up with them and make them appear to flash and flicker. They look fine to everyone at the track. |
