 Marker light

I had put a marker light on my BCD ( divers-supply.com/scuba-gear/lights/500hr-water-a...flashing-marker.html) while diving at night and one of the instructor yelled at me for doing so, telling me that the flashing sequence could cause epileptic seizure. Was he right telling me that? Does anyone know for sure if it could cause that kind of reaction???

From ELLOCODIABLO: Seriously doubt many epileptics get certed to dive

Agree, I don’t see that happening either. Back when I was USAF we wouldn’t let an epileptic drive a forklift and it had nothing to do with the strobe on top.

I have marker lights that blink too but once on a NJ night dive I attached my rescue strobe to the bottom of my dive flag float so it was about 18" underwater so boats would see the float. Before I even got underwater a USCG RIV arrived and told me the strobe was only for emergencies, a marker light would be okay.

I have several buddies that use these. I use a different type that isn’t bright like a strobe. I don’t think somebody with epilepsy will be diving.

I use the same marker light. I don’t think it flashes fast enough to trigger a seizure. Working as a paramedic for over 27 yearsI have only had maybe a few people tell me that bright flashing lights would trigger a seizure.

Fantastic, thanks everybody for your answers. I’ll keep using the light.
