The V-16 hazard pre-warning device is an amber-coloured autonomous light device, type-approved and with geolocation, that operates on its own power supply (battery or rechargeable battery). It must be placed on the highest part of the immobilised vehicle, ensuring maximum visibility. Currently, the V-16 is the only legal option for signalling an immobilised vehicle or an obstacle on the road, with warning triangles now obsolete.
