Running Lights Bright white LED provides 200 lumens brightness. These running lights come with a silicone cover that protects them from dirt and water. The Nighting running lights with strong magnetic can attach to any magnetic surface or be clipped anywhere.
Question: Does it come with a battery. How long does the battery last. Can you put it in water?
Answer: It charges by a USB cord, with no battery to ever replace! You just need to plug the cord into a computer or USB outlet to charge. I have used it on the 3rd solid light setting for about 4 hours total and it was still shining as bright as the 1st time. It has 3 solid settings and 1 flashing setting. Very bright. I'm extreme.
Question: Can this light be adapted to wear on the wrist?
Answer: If you've got a wristband on which to clip it, I believe it could be worn that way. I usually clip mine over the belt of my running pouch and it holds on well. I will say that the light is a couple of inches wide and rigid, so may not be the most comfortable thing to wear on your wrist, but worth a try if that's how you want to use it.
Question: Can it be used on winter coats?
Answer: Yes, I can. I have no problem with my cotton-padded jacket. The magnetic absorption function is very powerful.
