LED collars are pet accessories designed to enhance visibility and safety during nighttime walks. These collars feature built-in light-emitting diodes (LEDs) that illuminate in various colors, making pets easily seen by drivers and pedestrians. Typically made from durable materials, LED collars are adjustable to fit different sizes of pets. They often come with rechargeable batteries and multiple lighting modes, such as steady or flashing lights, allowing pet owners to choose the best option for their needs. These collars are popular among dog owners who prioritize safety during evening outings.
