Dear Mr T - why are we told not to look at flashing images on TV when cyclists conspicuously brandish their high intensity flashing lights? Surely it's a danger to motorists having continuously to readjust their focus;
and, what if they were photosensitive epileptics?
Dear Mr R - It is not illegal to use a strobing light provided the flash rate does not exceed 4 per second; at this rate it is considered safe. I hope I have been
able to answer your questions.
Dear Mr T - Actually, no you haven't. The epileptic society consider that a flash rate of 16Hz can bring on a seizure. It only requires 4 oncoming cyclists to generate this frequency
since it would be impossible to have perfectly synchronised flashing.
Dear Mr R - I’m sorry that we disagree on this particular point. It is my belief
that anything that can preserve cyclists’ lives is warranted. The horrendous accidents that befall them, both on our country lanes as well as in towns and cities, surely argues the case for them to
use the means they have at their disposal as vulnerable road-users to keep themselves safe.
Dear Mr T-
You keep missing the point: 4 times 4 equals 16. Recently, we have seen how vehicles crashing into pedestrians cause death and destruction. Should a photo-epileptic have a seizure on being confronted by a party of light flashing cyclists, he or she might crash
into the cyclists. Forget the pedestrians - they're not important - but the cyclists?
