Here is a funny story about those light-up headbands. Our Tico got an eye infection and needed to be treated every 2 hours round the clock. Putting medicine in a horse's eye that doesn't want medicine in his eye at 10, 12, 2, and 4 in the night takes two hands for sure.
So I wore my light-up headband, which sure helped a lot. But I discovered (never had noticed before) there were thousands and millions of spiders in the grass at night, and with the l.e.d. light on them, their eyes glowed. It was like walking through a field of little stars. Some of the spiders were pretty big and their eyes were kinda big, and other spiders were really small. Since I had to treat the horse for 3 days and 3 nights, those little sparkly eyes rather did feel like little friends.
