Solar-powered dummy alarm uses a light sensor to trigger flashing LEDs and includes USB backup charging. Compact dimensions and an aromatherapy diffuser option add practical versatility.


Automatic night activation - with smart light-sensing technology

A built-in light sensor detects low-light conditions and triggers the red and blue LEDs to flash automatically, conserving energy during daylight hours. The sensor removes the need for manual switching.

Hands-free night activation keeps a visible deterrent in place after dusk without user intervention, increasing presence during typical high-risk hours.

Continuous readiness - thanks to solar panel plus USB backup charging

An integrated solar panel charges internal circuitry during daylight, while a USB port provides an alternative charging route for cloudy days or shaded parking. Dual charging minimises downtime.

Reliable day-to-day operation relies on solar power with a straightforward USB top-up option to maintain flashing performance in poor light.

Fresh-smelling interior - with aromatherapy diffuser option

A slot accepts a scented wax disc so fragrance disperses from the mounted unit while LEDs operate. The dual-function design pairs a deterrent with a simple scent solution.

Combines security presence with a pleasant interior scent, useful for drivers who want both deterrence and a fresher cabin without extra gadgets.
