I made a sound reactive totem using a USB powered light strip from amazon and an Anker rechargable battery pack which I attached with velcro to the joint where the top of the totem connected to the pole. It was a good option because I could remove the battery and put it in my backpack (and even use it to charge a phone) when the totem was disassembled or not in use. I'd recommend this over getting lights that have their own AAA battery.
