The best V16 warning lights 2025 – comparison, test & buying guide

Introduction: Why buying now is worthwhile

From January 1, 2026, the V16 warning light will be mandatory in Spain.
Then classic warning triangles will no longer be allowed – only the "V16 conectada", the connected version with GPS and DGT connection, is approved.

Many drivers are still waiting, but early purchase has clear advantages:

  • You avoid shortages shortly before the deadline.

  • You benefit from low prices and longer service life.

  • And you already increase your safety in case of breakdowns or accidents.

This article offers a comprehensive buying guide for 2025, explains what to look out for, which brands are reliable, and which models already have the DGT approval.

1. What makes a good V16 warning light

Not every yellow lamp is automatically legally compliant.
The Spanish traffic authority DGT (Dirección General de Tráfico) sets strict technical criteria that every approved V16 must meet.

✅ Basic requirements according to DGT:

  • Light color: Yellow (Amber)

  • Visibility: 360° all-around light

  • Range: At least 1 kilometer

  • Lighting duration: At least 30 minutes continuous operation

  • Protection class: IP54 or higher (dust and splash water resistant)

  • Temperature resistance: –10 °C to +50 °C

  • DGT homologation number: Officially registered and printed on the device

  • For connected models: integrated GPS and GSM module

A model that does not meet these requirements is not permitted – even if it looks similar externally.

2. The two main types: simple and connected models

Currently, there are two categories of V16 lights on the market:

🔹 1. Non-connected V16 lights (transitional models until 2025)

These versions meet all optical safety requirements but do not have GPS or GSM.
They are allowed until the end of 2025, after which they can only be used as a supplement.

Advantages:

  • Affordable price (€15 – €30)

  • No SIM or data connection required

  • Ideal as a short-term solution

Disadvantages:

  • Not valid from 2026 onwards

  • No automatic location reporting

🔹 2nd “Connected” V16 lights (mandatory from 2026)

These models have an integrated communication module that automatically sends the vehicle position to the DGT 3.0 when activated.

Advantages:

  • Legally compliant from 2026

  • Real-time notification to authorities & navigation systems

  • Partly includes 10 years of data service

Disadvantages:

  • Slightly more expensive (€35 – 80)

  • Data transmission takes place via mobile network (SIM integrated)

Our advice: Those who buy today should go directly for the Connected version.
