What does '360-degree illumination' mean in practice — is the entire necklace lit?+
360-degree illumination means the LED light is visible from any horizontal angle around the dog — front, back, left, and right. This is achieved by the necklace wrapping around the neck circumference rather than attaching a single front-facing light. A driver approaching from any direction will see the light, unlike a collar-mounted LED tag that only illuminates one side.
What batteries does it use, and how long do they last?+
The necklace comes with two CR2032 coin cell batteries pre-installed. CR2032 batteries are widely available in grocery stores and pharmacies. Runtime depends on mode — steady glow uses more power than intermittent flash. When the light dims noticeably, replace both batteries at the same time to maintain consistent brightness.
How do I cut the necklace to fit my dog's neck, and what happens to the LED function at the cut end?+
The cut-to-fit design uses a continuous tube of LED material that can be trimmed with scissors. Trim from the non-connector end. The LED circuit runs the full length, so cutting reduces the number of lit segments slightly, but the remaining length continues to function normally. A secure seal or end cap at the cut point prevents the raw edge from fraying.
Is this weatherproof for use in rain or snow?+
The necklace is built to withstand various weather conditions including rain and snow, as stated in the listing. The LED housing and battery compartment are sealed against moisture. This makes it suitable for year-round outdoor use in regions with variable weather, unlike standard battery-based accessories that fail in wet conditions.
Can this be worn alongside a regular collar without interfering with the fit?+
The LED necklace is designed as an add-on safety accessory, not a collar replacement. It sits around the neck independently and is trimmed to the correct circumference, allowing it to rest alongside a standard collar without compressing it. The lightweight construction means it does not add meaningful weight or change the collar's position on the neck.
