Quickly - No.Maz said:Can a flashing LED give a driver an epi?
The trigger for epileptic fits is due to intensity, as well as frequency. That is why strobes and flashes can trigger an episode.
The trigger frequency varies between three and sixty hertz (flashes per second) and is typically sixteen to twenty-five.
No bike light on the market flashes at these rates, no lights on the UK market flash with this type of rate. Most are more than one hertz.
There have been reports of incidences, but these have been whilst setting up and it is suggested that it was the brightness due to close proximity rather than the flashing that was the cause.
In summary the chances of triggering an epileptic fit does not need to be a factor considered when buying bicycle lights.
