Safety Collars and Leads. Protects your dog in 3 ways: when it's in the "off" mode, the bright yellow surface is highly reflective. When the light is turned on, you can set it to glow a steady, bright red or to flash rapidly. When lighted, it's visible up to one mile. The Safety Collars are designed to make pets immediately visible…and safe…in the darkness and under any weather conditions. The Safety Collars don’t just reflect light; they also radiate their own light, providing maximum protection in low light situations. The Safety Collars are lightweight, weatherproof, shock resistant and capable of operation up to 250 hours on the included lithium battery. (Now comes with an extra spare battery, too!) The Safety Collar has been developed using a combination of (3M) Scotchlite and a unique, patented optical illumination technology. This technology disperses intense light through a nearly indestructible, flexible lens, which is illuminated by a red flashing LED light. The Safety Leash is lightweight, weatherproof, shock resistant and capable of operation up to 250 hours under the power of the included lithium battery. (Now comes with an extra spare battery, too!) This leash has been developed using the same optical illumination technology that is featured in the top selling Safety Collars. This technology disperses intense light through a nearly indestructible, flexible lens, which is illuminated by a red flashing LED light that can be seen from both sides of the leash. Protect your dog and yourself on nighttime walks with our Safety Leash.
