The Spotlit® Rechargeable Collar Light Disc-O Tech™ features an innovative LED module allowing you to choose from four selectable colours of red, green, blue or white. The built-in memory remembers your last colour setting, automatically turning back on in that setting. Simply push the durable, weather resistant body to illuminate, perfect for clipping to keys, bags or zippers. Charge up the light in 2 hours via micro USB cable (not included) to search for things in your car, navigate dimly lit spaces or get someone's attention from a distance.
