Not a long ago, I bought these wacky laces along with some other items from this site. I ordered them thinking to myself "These sound wacky". Well now I have them and I can say they work as promised and they sure are "wacky" in a sense.
They work in the way that you can take off the "laces" from both sides of the device that controls the LED lights.
There are 3 settings for the light; Constant glow, blinking and fast blinking.
Have to say that they're super bright and will catch anyone's attention.
They're a bit hard to attach to the shoes of choice but obviously they're made for people who "party" or like being center of attention anyway. Hopefully no epileptic people walk around me while wearing these.
I haven't tested these around in wet weather yet, but they're waterproof.. at least the laces will be.
