Vehicles with faulty lights are allowed to circulate, provided they have:

In case of a lighting system malfunction, the vehicle's circulation is allowed so that it can travel to a repair or parking location, provided it has minimum safety and visibility conditions. At the front, the operation of the left-side dipped beam and both parking lights is mandatory. At the rear, the left-side rear position light and at least one of the brake lights are required, if mandatory. The other options are incorrect because they indicate the operation of the right-side dipped beam. The mandatory operation of the left-side lights (dipped beam and position light) serves to ensure that other road users, especially those traveling in the opposite direction, can correctly identify the left lateral limit of the vehicle, avoiding collisions.
