The Company of Animals has launched a new range of battery-powered, illuminated dog leashes and collars called Visiglo.

Available in 5 designs ('Bones', 'Macaroni', 'Paws', sport stripe and flashing LED), these look to me at least like an accessory that could sell really well in practice. They look nice, serve a useful purpose (as well as making the dog more visible to traffic, the collars would presumably make it much easier to see where he's gone when out walking off the leash after dark). There's a video here.

 
Plus, with Christmas coming up, it's the ideal stocking filler for all those people that do their houses up like Blackpool Pier, and want the dog to look like a Christmas tree.

Visiglo is (or will be shortly) available from the veterinary wholesalers.
