IMHO typical flashing bicycle headlight doesn't seem likely to induce a seizure. No more so than any of the flashing or strobe lights used on myriad vehicles - police/fire/ambulance/tow/roadcrew/etc.
Here's an interesting article:

Seems the most troublesome frequency range is 10-20 flashes per second and must cover enough of the retina - neither of which would seem to be an issue with an oncoming bicycle headlight.
All that said, I don't think a bright flash (or really any light) is needed on a rural hiker/biker trail.
