QUOTE (BobB @ 6 Feb 2009, 13:01) <{POST_SNAPBACK}>What about getting a flasher unit from a car scrap yard, they work on anything from 7.5 to about 40 V smoothed and eratic DC. Might be cheaper !
I'd agree with poliss - yes, vehicle flasher units operate on a wide voltage range but they need far more current going through them than a couple of led's to actually flash.
