These items are awesome! The LED wristbands and vest have a button you can push to activate the LED light. There are three modes: Bright steady light and slow or fast flashing (and obviously off as well). The vest is adjustable which is nice, because I'm petite and was worried it would be too big! I really like how bright these are and how it comes together on your back as well. It works great and really helps make my presence known (and my dog's presence as well). I like to put one of the wrist straps on her harness so people can see her too.
I would highly encourage anyone who walks at night to get this. When it comes to your safety, there are just some things you should not cheap out on, and it's not even that expensive compared to other vests I've seen that don't even have LED lights! I would recommend this!
