What Is the V16 Emergency Light

Starting January 1, 2026, Spain will require all vehicles to carry a V16 emergency light instead of the traditional warning triangle. This compact, battery-powered beacon emits a 360-degree flashing yellow light and is placed on the vehicle’s roof to signal distress without the driver needing to exit the car.


Battery Basics: What Powers the V16

Most V16 lights are powered by long-lasting lithium batteries designed to function reliably in extreme conditions. Key features include:

Battery life: Typically 2–5 years, depending on the model.

Activation: Instant-on with a single press, even in low visibility.

Connectivity: Advanced models include geolocation features that transmit your location to Spain’s traffic authority (DGT).

Regulations and Compliance


To be legally compliant in Spain:

The DGT must approve your V16 light.

It must be visible from 1 km away in all directions.

It must operate independently of the vehicle’s power system, meaning battery-powered is mandatory.


Pro Tips for Drivers

Check the expiry date on your emergency light’s battery.

Avoid cheap knockoffs—only DGT-approved devices are legal.

Store it within reach so you can activate it without leaving the vehicle.

Spain’s push toward smarter, safer roadside signaling is a win for everyone. Whether you're a local driver or a tourist, investing in a reliable V16 emergency light with a robust battery isn’t just smart—it’s the law.
