Now in one of the most popular sizes, we have brought a 5mm round top blue / red alternating flashing LED that flashes at a rate of approximately 1.5Hz. It will flash between blue and red at this rate. The rate equates to approximately 90 times a minute. This cycle will repeat as long as there is power to the LED. The 3mm round top 1.5Hz blue / red flashing 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.
We use and have only the highest quality leds out there.
