Pebblebee, a Seattle-based tech company, has launched the Halo - a keychain-sized device that can track lost items, provide lighting in dark areas, and activate a 130dB siren to alert contacts in an emergency. The Halo is designed to provide personal safety features in a compact, easy-to-carry form factor that integrates with users' everyday routines.

Why it matters

Personal safety gadgets have often struggled to gain mainstream adoption, but the Halo's combination of tracking, lighting, and high-decibel alarm functions in a familiar keychain form factor could make it a more practical and useful tool for people looking to enhance their personal security, especially in situations like late-night campus walks, solo runs, or navigating unfamiliar cities.

The details

The Halo device weighs just one ounce and clips onto a keychain. When the device is pulled apart, it activates a 130dB siren, a 150-lumen strobe light, and shares the user's real-time location with up to five trusted contacts. There is also a silent alert option that sends a notification to the user's safety circle without triggering the alarm. The Halo works with Google's Find Hub on Android to help locate lost items, is water-resistant, and has a battery life of up to one year on a full charge.

  • Pebblebee launched the Halo device in April 2026.
