I was given about 12 feet of reflective tape, and a BikeGlow light about 6 weeks ago. I put the tape on the dogs' harnesses, and on several places on the front and sides of the sled. (I also taped my kids' snow pants, but that's not part of this story) and mounted the BikeGlow to the steering handle of the dogsled. Black tape doesn't work very well in sub freezing temps, and must be replaced often. IT IS WELL WORTH THE LITTLE BIT OF TROUBLE of replacing the tape. Whoever is driving my sled is required to wear an orange safety vest. My wife got so far in front of me a few times last night that all I could see of my team and family were 4 strips of tape on the vest and the BikeGlow. When they moved out from under the pool of trail lights, I couldn't see the vest, but could still see the glowing light. Lighting is difficult in the winter, because batteries must be kept warm or they will not work. I have a 6 volt lantern that I aim at the dogs to use as a headlight and to provide them with the direct light they need the tape on their harnesses. It comes inside after each run. Even though I broke the plug clip on my Bikeglow (I kept the battery pack in my pocket, then stepped off the sled...my mistake) it still works like new. The removable battery pack is my favorite feature on these lights. It takes me 2 minutes to mount my headlamp, but only seconds to light up my steering handle.
