The ROCKBROS Ghost Elastic is a compact, ghost-shaped warning light designed to keep you visible during nighttime activities. It features three lighting modes—steady on, low brightness, and flashing—all of which are easily managed via a single button. To ensure reliability in various weather conditions, the device is built with an IP64 dustproof and waterproof rating and encased in a soft silicone shell. Powering the light is a rechargeable lithium battery that charges fully in just one hour through a modern USB Type-C port. Its standout feature is the integrated elastic band, which allows you to quickly secure it to a bike seat, helmet, backpack, or even your clothing. This lightweight design makes it a practical safety accessory for cyclists, runners, and pedestrians who need a versatile light that can be moved between different gear as needed.
