This is a video of Toby's night-light collar; white flashing leds on the back of his neck, red flashing leds hanging below his neck. Although difficult to tell, the flashing white leds can be seen at least 1/4 mile away. I know snowmobilers appreciate the early warning that these lights provide. Plus I always know where Toby is!
