We don't sell or endorse many products from other companies but we really love the SpotLit from NiteIze and it makes a great addition to your Air Collar.
So many uses, so little time. Perfect for your dog's collar! You can also attach it to your zipper, keys, purse, backpack, bike, or stroller, or keep one in your glove box or gym bag ... the possibilities are endless. The SpotLit has a clip that allows for quick and secure attachment.
