Could my flashing front lights cause....

[Cubist]

No, really, try it (you can turn off straight away afterwards if you object to Eastenders). Try and look at the centre of the screen as the scene revolves outwards, and then keep staring when it stops. The middle bit seems to turn back...

Unless it is only me...

I'll give it a go, but wonder whether it'll do it on a HD ready LCD screen. And if I'm exposed to more than a few seconds of Eastenders I'll visit you in the small hours and put a bat up your nightie.

Well, if you have a fancy telly... I'm not sure the telly should make a difference, I've always assumed it was an effect of the eye, not the screen.


Like that trick where they show a union jack but in odd colours, and tell you to stare at it, and then flash up a white screen and you see the right colours briefly.

Oh, and I don't have a nightie, I'm afraid, it's snuggly jim jams for me.

We seem to cause quite a few fits, but they generally arent Epileptic ones.

Can't you get the same hypnotic type effect with traffic cones flashing past on motorway roadworks?

If anyone fancies some proper side-on nighttime illumination have a look at spoke POV

The Greenwich Foot tunnel, used by many hundreds of cyclistis every day, has for a number of years banned cycle lights (and photography) for this very reason.

One of the lift operators suffers from this form of elepisy

I laughed out loud at that and beleive me, that is quite an achievement!!

The Glasgow subway always runs slow when it's passing an area where work's been going on and the white lights are still on in the tunnels.

One time a couple of years back, the train I was on didn't slow, and a guy in a carriage further back apparently started fitting. From the weary way one of the subway staff at the next station (picking litter or cleaning the platform) told this to the driver, it obviously wasn't too unusual. (Naughty driver!)

an epileptic fit???

I stopped to help some guy who had collapsed by the side of the road, turns out he had had some kind of fit, I called the ambulance and waited for it to come. DJ

Well done with the good samaritan bit!

Never heard of flashing l.e.d. bike lights being linked with fits before - interesting to hear what the others had to say.

Is that the same effect as when I see the wheels on John Waynes wagon going the opposite way to the way they should be going? Especially when there is a whole tribe of Apache's after him the effect is amazing!!

Sounds similar to when you see car/biclycle wheels through the rungs of a roadside barrier, the wheels look stationary or going backwards.

I've never nopticed that before will try it tomorrow.

Same principle, the image of rotation is being interrupted by the rungs....

Whilst it's unlikely for flashing bike lights to trigger an epileptic seizure, they can be distracting for drivers. Mind you, that's the point isn't it, to distract them out of their post-work I-just-want-to-get-home torpor
I would imagine there's more chance of migraine sufferers being affected than epileptics, if my experience gathered from watching my mother-in-law is anything to go by. She has to cover her eyes if she is near a strobe light (eg a stage show) or there is flash photography on the TV.

As a migraineur, that's the one thing I really don't like about flashing bike lights. It's just sometimes a bit close to the start of an aura for me when I see them.
Having said that, they're not generally in my vision for very long. If I'm in the car, then I will be past the cyclist in fairly short order. If I'm on the bike, then they will be way ahead and out of my view in very short order. So not really an issue.
I tend to use my lights on not-flashing, though, just because I know my eyes aren't fond of flashing lights.
