Madrid – The European Commission is questioning the legality of Spain’s recently implemented mandate requiring all drivers to carry a V-16 warning light, a device intended to replace traditional warning triangles. The move casts a shadow over the roughly 28 million Spanish drivers who have already purchased the lights, costing around €50 each, and raises concerns about potential trade restrictions within the European Union. The core of the dispute centers on Spain’s decision to equip the V-16 with geolocation technology and connect it to the DGT 3.0 platform, a move Brussels argues was not properly notified and may violate EU regulations.
The V-16 emergency light, a small LED beacon designed to emit a high-intensity 360º light for up to 30 minutes, was introduced at the start of 2026 by Spain’s General Directorate of Traffic (DGT). The intention was to improve road safety by eliminating the need for drivers to exit their vehicles to place warning triangles in the event of a breakdown, a practice that has reportedly led to 25 deaths annually in Spain, according to Interior Minister Fernando Grande-Marlaska. However, the requirement has been met with criticism from various sectors, including law enforcement and consumer groups.
EU Concerns Over Geolocation and Notification
The European Commission’s concerns, detailed in a response to a parliamentary question, stem from Spain’s failure to notify the EU of the new regulations, as required by Directive (EU) 2015/1535. This directive mandates that member states inform the Commission of any draft technical regulations before their adoption, allowing for a three-month review period. Executive Vice-President Séjourné, speaking on behalf of the Commission, stated that “the Spanish Royal Decrees have not been notified according to the procedure of Directive (EU) 2015/1535.”
Beyond the notification issue, the Commission is examining whether the requirement for geolocation connectivity and integration with the DGT 3.0 platform constitutes a restriction on the free movement of goods within the EU. The principle of free movement, enshrined in Article 34 of the Treaty on the Functioning of the European Union (TFEU), aims to ensure that goods can circulate freely between member states without undue barriers. Spain would need to justify the requirement under Article 36 of TFEU or based on established jurisprudence from the Court of Justice of the European Union (CJEU).
Criticism and Doubts Over Effectiveness
The V-16 light has faced criticism on multiple fronts. Spain’s Civil Guard police, in late 2025, questioned the device’s effectiveness, particularly on winding roads where the light’s visibility is limited. They too raised concerns about its brightness during daylight hours, suggesting it may be insufficient to adequately warn oncoming traffic. These concerns echo doubts cast over the device’s overall utility, despite its intention to enhance safety.
Adding to the controversy, reports in the Spanish press have highlighted that the inventors of the V-16 light initially conceived it as an aid for drivers with disabilities, not as a compulsory device for all motorists. This revelation has fueled further debate about the appropriateness of the mandate. Consumer watchdog Facua has criticized the Spanish government for failing to provide clear guidance to drivers on which V-16 lights are officially recognized by the DGT, leading some to purchase non-compliant devices.
Potential Consequences and Next Steps
If the European Commission determines that the Spanish regulations violate EU law, Spain could be forced to amend the rules. This would have significant implications for both drivers who have already purchased the lights and manufacturers who have adjusted their production lines to meet the new requirements. The financial impact could be substantial, given the widespread adoption of the device.
Spain’s Interior Minister Fernando Grande-Marlaska is scheduled to address the Spanish Congress on Wednesday, February 25th, to provide an update on the implementation of the V-16 emergency signaling beacon. This appearance comes as the legal questions surrounding the device intensify and as drivers await clarity on its future. The Commission’s investigation is ongoing, and a decision is expected in the coming months, potentially reshaping road safety regulations in Spain and setting a precedent for other EU member states.
The situation underscores the importance of adhering to EU notification procedures and ensuring that national regulations do not unduly restrict the free movement of goods within the single market. For Spanish drivers, the outcome of the Commission’s review will determine whether their investment in the V-16 light was a necessary safety measure or a costly and potentially unlawful requirement.
