Detect Urine Stains Urine can be hard to spot, especially on dark carpets. This flashlight, however, sidesteps the dreaded bend down and sniff method by incorporating 12 UV LEDs and a 395-nanometer wavelength that can illuminate dry and wet accidents. Use it on floors, clothes, furniture, and any other surface your pet may have been savvy enough to squat on. Authenticates IDs The flashlight also authenticates drivers licenses and passports, giving you all the power of an especially stern bouncer. This should help you keep underaged yahoos out of your house party or bar, but, more importantly, it confirms whether or not theres pee on the ID. Specifics Helpful for cleaning up during housebreaking or for an older pet Durable aluminum construction Requires three AAA batteries (not included) Product dimensions: 1.18×1.18×3.74 Weight: 3oz.
