PlugsSafety PSHL01 HatLight Plus clip-on articulating hat light is a clip-on, high-impact polystyrene light that attaches to the bill of a standard baseball cap and articulates to direct the light in a range of positions. It has two white LEDs and one red LED which can be adjusted with a three-way switch to shine a steady white light, a steady red light, or a flashing red light. The high-impact polystyrene body is more flexible than other plastics to resist cracking and breaking. The removable light module doubles as a handheld flashlight. The light includes two replaceable CR-2032 3V lithium batteries. It weighs 0.06 lb. and measures 0.75 x 2.75 x 1.5 inches (H x W x D). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.)
