I know this may sound a bit off topic, but do they make any strobe devices that are epilepsy friendly?

Wish they did!... And a flashing strobe can also trigger an opthalmic migraine in those of us who suffer from those! Any pulsating light source will do that. It isn't fun :shock:

(Opthalmic migraine is when you see a wiggling disturbance in your field of vision, then it spreads to where you cannot see, then you begin to see a little in the center, then after 15 minutes you see OK again but with a BAD headache and hypersensitivity to light or sound. Whole miserable cycle lasts about an hour)

Unless located not too high, strobes like that are fairly worthless.
Washed out in daylight, even overcast, therefore
few notice them and know what they mean.

Siren is much better notification.

If you wish, please see Strobes and Siezures under General Non Siren Discussion.
Thank you,

hey i know its a bit off topic but jim do you know what a metal plate thats about 8"x8" square. thats divied down the middel and one half is white and the other blue or one is yellow and the other is blue . there usaly found in the middel of the rails on the ties between the rails. any clue? i got them off an abondon rail line.

Those are tiedown plates. They are placed underneath the rails to form a sturdy base for the rail to lie on the railroad ties. Without them, the stress would destroy the ties, and the rails with them.

Wuh? They come in colors?
Sounds like something else. Signal junction box covers?

I think that Douro meant the plates that reduce pressure and friction densities on the ties.

We call those tie plates.
I've never seen them in colors.

Also he said they were in the middle of the rails.
Middle of track between the rails?

Tie-plates don't come in colors, yes.

Then what he is referring to might be a block.

strobe lights usally red or blinking red like by a metal cover on street corner or box may mean Lift station failure in teh city sewer system. I see alot of that in small towns and around lakes that have put in serwers systems. IN WI all the school bused have white strobes on the back.

I'd hope the lift station failure would send notice via radio or telephone so that the problem would be immediately handled.

What a stupid very expensive waste of money installing white strobe lights on a school bus.
White should be reserved only for emergency vehicles.

Yellow is a much more noticeable signal.
