A note for night-time horse brushers: If your horse brush light does strange things, be sure to purchase our flashlight after the lantern or night vision (you can sell the flashlight and re-purchase if you already had it before getting the lantern or night vision). Alternately, purchase the night vision goggles last to have night vision horse brushing!
