Are passenger cars towing a light trailer required to carry an approved fire extinguisher among their accessories?

When travelling with a trailer, we are not required to carry a spare wheel for it, but we are required to carry a fire extinguisher. In any case, whether travelling with or without a trailer, we must always carry: - A hazard pre-signalling device (an auto-yellow coloured device with autonomous power supply (battery or accumulator) to be placed as high as possible on the immobilised vehicle, ensuring maximum visibility. - A spare or temporary-use wheel (for the passenger car) and tools for changing it. - A reflective vest.
