Chasing Christmas Lights - 140 bulbs to the light string
The bulbs on these light strings are constructed with 3 circuits that turn on sequentially - one, two, three - at a rate you chose with a controller box.
Used in a straight line, the alternating lights will look like they are "traveling".
Randomly bunch them together on a shrub or in a container and they'll appear to randomly twinkle on and off.
These mini light sets have one stackable male plug only. (You can stack up to 2 sets together at one plug but you can't connect them in series.) These chasing Christmas light sets are approximately 46 feet long with 4-inch bulb spacing.
