The 3mm flashing round top yellow/gold led will automatically start flashing once it is appropriately hooked up to power. There is nothing extra needed when hooking this led up to power. A power source, led, and resistor is all you need. 6Hz = 6 cycles per second or about 360 times per minute. It will flash on and off 6 times each approximately per second. We consider this an "ultra fast" flashing LED. The frequency is approximate.We use and have only the highest quality leds out there.
