mpja.com has 10W LEDs for $= 2.95 each. Each strobe takes three of them. You also need the 3= 0W power supply for each strobe. Another $8.95. I've put a scop= e on the input and output. It doesn't generate much in the way of noi= se. Just a constant current.

There is a seller on Ebay selling "Grimes wingtip l= ight". You can get two for $16 or one for $6.

In America, any of the chain aut= o parts stores carries the EP36 flasher from Novita. Takes one for mo= re strobes than you'll want to run.
