Depending on how electronic savvy you are, this would work. Just add a switch between the power source and the rest of the circuit.

I searched the Bay but couldn't find one. Please provide your search criteria, or a link.

Thanks to all. I need it in yellow. I knew someone would come up with a circuit involving the ubiquitous 555.

It's been probably 25 years since I'd seen anything with the 555 timer....Funny that I was thinking the other day about that very circuit.

Digikey has the yellow ones T 1 3/4 for about $1 ,8,400 in stock I think they also have some T1 $3 ,3 min. T1 is probably what you want for roof flashers ? in HO ?

There are loads of 555 timer / modules / kits / boards on ebay,
the link Rico provided also has yellow flashing LEDs ,

Keep in mind , Its hard to recommend an exact fit without knowing what the application is .

looks very similar to the one I photographed, the capacitors might be a bit smaller, but not a big deal ...
the default rate was about 1 flash per second .. the price is a bit higher, but not much either ..
