The clip grips most flat collar straps, harness loops and leash rings. It suits small and large dogs alike, since it rides on the strap rather than around the neck, so you do not need a particular collar width to use it.

No. The sealed housing is small and light, so a small dog walks normally with it clipped on. It sits low on the strap and most dogs settle into the walk without paying it any attention after the first minute.

Steady reads as a calm glow for general dark-walk visibility down quiet streets and gardens. Flashing catches a driver's eye sooner on a busy or fast road, so many walkers switch to flashing near traffic and back to steady for the calm stretch.

Each light runs on a button-cell battery housed inside the sealed plastic body. There is no cable to charge, so the light is ready the moment you clip it on and press the button by the front door.

The housing is a sealed lightweight plastic that keeps the battery and LED dry through dew, drizzle and a wet field. It is made for everyday evening and early morning walks rather than for swimming or being left underwater.

Choose a 2, 4 or 8 pack at checkout. The larger packs are handy for households with more than one dog, for keeping a charged spare by the door, or for clipping more than one light on a bigger dog for extra visibility.
