I love this light. I have a brown English Springer Spaniel mixed with Blue Merle Austrailian Herder. 98% of his white hair is on his under portion, making it almost impossible to see her in the dark if she wonders off. Since I use this in the flashing mode, no problem. I use it for going for walks, when we are RV'ing or late evening strolls in the bush. I feel safe & I think she feels safe too.
