Flashlights are great but you need to be able to find them in the dark! The Spark easily attaches and is unobtrusive when holding the flashlight. The are also great for those smaller sets of keys (like your workshop cabinet key ring) that are always in the dark.

Andy loves his glow bling! He lives out in the middle of nowhere and when there is no moon its totally black outside. These little sparks look like a blue eye zooming around the farm 6 inches off the ground. Best use I have found for these yet.

We have purchased several and love them. Easy to see at night and it is high on the “cool” factor. Will be purchasing many for Christmas gifts.
