Every colour reaches the same distance. All 11 colours of the Orbiloc Dog Dual are visible up to 5 km, verified by an external light lab. What changes between colours is how bright the light looks up close — to you and to other people nearby. The intensity score below (out of 5) measures that up-close brightness, not how far the light reaches.

This means there is no wrong choice on safety grounds. Choose by what suits your dog’s fur, your collar colour, or the situation you walk in most.

Yellow — Brightness: 4/5
Warm and easy to notice. Gentle on the eyes when your dog walks close to you.
Good for: on lead, in town, in the countryside.

Red — Brightness: 2/5
A familiar signal colour. Easy on your night vision, softer up close than green or white.
Good for: off lead, on lead, countryside.

Blue — Brightness: 3.5/5
Uncommon in everyday lighting, so it stands apart from streetlights and car headlights.
Good for: off lead, in town, in the countryside.

Green — Brightness: 5/5
One of the two brightest-looking colours up close. A clear signal against dark fields.

Bright and clear, and the best choice for dogs with long or thick fur that may partly cover the light.

Pink — Brightness: 2/5
A bright, playful look. Mixes purple and red light so it appears softer up close.
