Is the amber strobe legal to use at night in traffic?

The 8×32 amber strobe is a pedestrian visibility aid — like a handheld flashlight — not a legal traffic signal. Point it toward oncoming traffic while you cross, and never aim it at drivers' eyes at close range.

How do I reset the poop-bag loop tally between walks?

Swipe Pad 4 to zero the tally and scroll LOOPS 00 · WALK START. Pad 3 double_tap adds one loop each time your dog does its business so you never double-bag or walk off without one.

Will the strobe drain the controller overnight?

With a user-supplied USB-C power bank (no battery is included in the box), the 256-LED amber strobe at full 255 brightness is estimated to run about 3 hours. Hold Pad 5 to drop to 25% between crossings for multi-hour night walks, or switch Pad 2 to steady for a long low-power glow.

Dog-Walker Night Crosswalk Light-Pattern Strobe & Bag Tally

Be seen and count the loops: a 256-LED amber crosswalk strobe fires from Pad 1 while the 8×32 matrix tracks your poop-bag tally — $199 finished sleeve.

A crossing signal, not a reflector: A 256-LED amber strobe on your raised forearm is designed to be visible from roughly 300 feet.
Tally while you leash: 5 sewn fabric pads count bag loops and switch the strobe to steady with the leash in your opposite hand.
Ready out of the box: Ships as one of the 50 built-in modes; set strobe speed and colors in the Sleeve Studio app.

Why Reflective Strips and Phone Torches Fail on Night Walks

Reflectors need a headlight: A vest only lights up when a car's lamp hits it, and a phone torch blinds the dog and drains your battery.
Yours is always on: The strobe is directional and active, so drivers read it in rain and fog as a clear crossing signal.
Hands stay on the leash: The tally and strobe run elbow-to-wrist while your opposite hand holds the lead.
