Arch I had a couple of fits when I was younger the first was the day after my higher exams (final exams at high school) technically I could of been driving at the time but I had decided to put off having lessons till after my exams ;)

Yup, I have a friend who suddenly developed epilepsy a couple of years ago. Luckily it's all under control now, and she can drive again, but it made things difficult, with her living out in the country, several miles from a bus route. The doctor said she shouldn't even cycle, but she chose to ignore that, since she was only endangering herself and would have been completely without transport apart from taxis...

Can a flashing LED give a driver an epi?
Depends on the LED I guess, most wouldn't but my Lupine Wilma LED (15W off road LED) has a 'super flash' mode that is very strobe like. The instruction manual urges caution in it use, presumably for this reason.

Right oh then, Hairy, and if you've never had a fit, and then you suddenly develop epilepsy, you're going to know you're suseptible, how exactly? Plenty of people have their first fit in adulthood, and could easily have it behind the wheel of a car, driving perfectly legally...
In which case the fit is as likely to triggered by a faulty street lights or driving down a tree-lined road on a bright sunny day... fortunately developing epilepsy is very rare, other wise we would have to go without streetlights and cut down all the trees. It is not a reason to stop using LED bike lights...

The flash modes of the higher end LED based lights such as Lupine, Dinotte etc are reffered to as strobes and can trigger epilepsy. But then on a moving bike, it's quite rare unless the person is directly behind you and you're shining the Dinotte straight up.

For the record, in built up areas I prefer to use the strobe feature as it's more attention grabbing and shouts bike.
 
Sorry,,,

I made two assumptions,,,

1. I was considering all other users when I answered the question - pedestrians and other cyclists as well as drivers. For these groups there are no restrictions, and hence a vulnerability.

2. I had considered the "average" off the shelf LEDs, NOT the big hitters such as the Dinotte.

I do not use the Dinottes in flashing off road, but do on road for the reasons that Valiant states.

No, I know, I didn't say it was. I was challenging your assertion that someone with epilepsy shouldn't be behind the wheel, on the grounds that they may not know of their condition. Your post seemed to me to be suggesting that if someone had a fit while driving, they were somehow at fault, when they may be perfectly innocent of the risk and it may be their first ever fit.

I would be interested to know what the statistics are for accidents involving pedestrians and cyclists in Japan.
I daresay they are insignificant compared to the risks of being trampled on by Godzilla or shot at by giant robots.

Apologies. It's just that he used the exact same phrase in a different thread yesterday...:blush:
