Illumination has come full circle? literally. Nite Ize brilliantly durable NiteHowl LED Safety Necklace is made with a flexible polymer tube? illuminated by two bright red LEDs? that simply slides over your dog's neck for hours of nighttime fun &amp; safety. Just trim the tube to a custom fit? give the button on the durable? weather resistant housing a quick press? and the entire collar lights up a full 360 degrees? making your dog clearly visible from all angles? coming and going. The LEDs can be set to either flash or glow modes - great for differentiating more than one NiteHowl-wearing dog. But? as fun as it is (like a neon necklace for dogs!)? the best thing about the NiteHowl is that it keeps you and your buddy seriously safe on those after-hours walks? romps in the park? and campsite moon-howling sessions.<br><br>Features:<br><br>- Two Bright Red LEDs<br>- Easily slides over your dog's neck as a bright LED addition to an existing collar<br>- Features bright Red LED - Flash or Glow Modes<br>- 360 degree illumination<br>- Weather Resistant<br>- Features 2 x 1154 3V Replaceable Alkaline Battery<br><br>Specifications:<br><br>- Universal Sizing: Fits 12"- 27"<br>- Battery Life: 60 Hours<br>- Dimensions: Adjustable Length 12" - 27" x .3" Diameter<br>- Weight: 2.1oz
