How long does the battery actually last?

The maker claims up to 20 hours. Expect much less on the brightest white or flashing modes, and charge it after a few evening walks until you know your own runtime.

Is it really waterproof enough for a swimming dog?

It carries an IP68 rating and the maker cites 5 m depth. Rinse and dry the charging port cover after water use to keep the seal working.

Will it fit my dog's collar?

It clips onto a collar or harness strap rather than threading on, so it fits most standard webbing collars. Check the clip opening against very thin or very wide straps.

How do I tell two dogs apart?

Each light has a steady color mode and an RGB alternating mode. Set one dog to white and the other to a fixed color so you can identify them at a distance.

Does it come with charging cables?

The pack contains two lights. Confirm the cable and charging method in the box contents before buying, since USB cables are sometimes not included.

Is it too heavy for a small dog?

At about 0.53 oz it is light for most dogs, including small breeds. On a toy-breed collar the clip may feel bulky, so a harness strap is a better mount.

Our take on the Rechargeable LED Dog Collar Light, 2-Pack

This is a two-pack of clip-on LED lights for dog collars, each with seven LEDs rated at 80 lumens and four modes: steady white, steady color, flashing color and alternating RGB. They recharge over USB instead of taking disposable batteries, and the maker claims up to 20 hours per charge and IP68 waterproofing to 5 m. At about half an ounce each they suit small and large dogs alike, and the two-pack lets you mark two dogs in different colors. Against typical button-cell collar lights they are brighter and rechargeable, but they are bulkier than flat tag lights and the runtime claim depends on which mode you use.
