Abstract: An illuminable dog, cat or other tethered animal leash and animal collar which contains a series of lights, such as but not limited to light emitting diodes, which series is externally mounted of the collar or leash, with spacing between each member thereof. The lights are electrically connected to wiring that is disposed within a recess(es) of the substrates used for the device. The wiring may be covered by an extra insulator and a sealant may be employed to close the gap along the junction of the two layers that are joined together with the wiring inside thereof. The mode of construction for both the leash and collar are the same. The series of lights may all be the same or a pair of colored lights or even multi-colored ones may be employed. These lights may be manually actuated or turned on via a daylight sensor. The bulbs may run constantly, though blinking is preferred, to limit heat buildup and enhance visibility.
