I have purchased three sets of these wires to make glow in the dark costumes for a school talent show. The wires worked very well and gave off a lot of color. I highly recommend this to anyone who is looking for a fun D.I.Y, there is a lot you can make out of these wires. From signs to costumes there is something for everyone and you will definitely get double the looks, as these really stand out with their vibrant colors. One of the first things to mention is that I love how low maintenance it is. Just like in the picture what you see is what you get, the wires are very sturdy and last a long time. I did a dance routine is this costume and the wires held is place for the whole four minutes without falling while the batteries were carefully tucked away in my pants. I love how versatile these wires are, you could make them into virtually anything with the right materials. For my costume I sewed cut up straw pieces onto my pants and just laced the wire through to keep them stable. As difficult as it sounds it hardly took anytime at all to make. Because of these wires I now have a really cool costume and great memories.
Bought to use for my son's. In the dark, the wire is decently visible. I would not say it's super bright, but acceptable. But during the day, hard to see. It's very flexible; was able to do 90 degree bends where needed, and works just fine after being cut to length. The Power adapter does emit a small, high pitched whinebut you can only hear it in relative quiet. For the price, the 5 pack was a good choice. Nice to have a solid, slow, and fast blink mode. It worked as expected..
I used these lights on a Halloween costume for my son. They were easy to work with and held up to all of my twisting and stretching as I sewed them to his clothing. The battery packs hooked easily on his belt and the wires stayed lit and unscathed thru hours of trick or treating.
Crazy-cool light-up colors! We put them on our fat bike wheels using tie wraps and it really sets them off on night rides. Everyone asked where to get them so they could add lights to their bikes!
