QuadSpark - the original 5mm LED strobe light string

QuadSpark 5mm LED strobe lights. The Christmas Light Emporium is the home of the original every 4th bulb strobing 5mm LED strobe light string - QuadSpark! It's our top selling product line year after year for a reason; we worked hard with our manufacturing partners to get them perfect! Nothing beats QuadSpark - the best quality, most 5 star rated, commercial grade, field tested every 4th bulb strobing 5mm strobe lights available!

This is not a twinkle string with a subtle on/off - this is a true *pop* LED 5mm strobe string that creates a fantastic effect in your light display.

This version has 3 static bulbs between each strobing LED - we designed them specifically for use in tree and shrub wrapping in static displays that want to add some really elegant sparkle. Every 4th bulb on this string strobes randomly to create the effect of tiny camera flashes. When wrapped around a tree, through shrubs or on any structure, this string will make your display sparkle.

These can be left on all night to create a magical environment.
