Flashing subway lights

Some people have trouble with flashing lights triggering epileptic seizures. My advice: avoid the subway. When I was in NYC, the flashing of the subway as it cruised by the platform tended to make my eyes flicker. I have never had problems with flashing lights causing seizures, but don't really want to push my luck. So after becoming somewhat dizzy at a platform, I spent the remainder of my time in NYC avoiding looking at the trains.
