This multi-functional safety accessory combines an audible warning system with bright LED lighting. Designed to mimic a police siren, the device features four distinct sound modes and bright flashing lights to ensure you are noticed in any environment. It serves as both a functional horn and a visibility aid.

The unit is powered by standard batteries, making it easy to maintain without waiting for a recharge. Its waterproof construction ensures that the electronic components remain protected during rainy weather. The integrated trumpet-style horn is loud enough to alert pedestrians and other cyclists of your presence on the path.

Designed primarily for adult bicycles, the mounting bracket fits securely on most handlebars. The controls are positioned for easy access while riding, allowing you to trigger the sounds or lights instantly. It is an ideal choice for those who want a high-decibel warning system paired with active lighting.
