Tri-Tronics' Tracer E-Collar Light is a lightweight, very brilliant LED light that lets you know where your dog is after dark. It is available in three colors and has a choice of two light modes: blinking and steady.

By using differing combinations of light color and mode you can identify multiple dogs. You can leave it on as long as required or switch it on only when needed. The unit is remotely activated by your transmitter and is compatible with any Tri-Tronics G2 or G3 EXP system. It attaches to the G2/G3 receiver in seconds and is powered by the receiver battery. Choose between constant and intermittent light modes. Other features include a 30-day money-back guarantee and one-year comprehensive warranty.
