Our solution was to use a 555 timer chip to drive a MOSFET to drive a 12VDC LED spotlight. The internet is filed with 555 timer chip examples so we will skip that discussion. The problem is that a 555 is fine for blinking a standard small LED, but a small LED doesn’t put out enough light to be used as a strobe.
