A measurement device and method for determining the angular position of a pivoting headlight by means of a measurement device that comprises at least one ferromagnetic element that emits a local magnetic field, first means of measuring the local magnetic field in projection on a first axis, the at least one ferromagnetic element being mounted so as to pivot with respect to the at least one first measurement means, and an electronic processing unit, the method comprising a measurement step, and a second processing step during which the electronic processing unit calculates the angular position of the headlight, that, during the measurement step, the intensity of the local magnetic field is measured in projection on a second axis orthogonal to a first axis, and that, during a second processing step, the electronic processing unit calculates a value representing the angle of the local magnetic field with respect to the first axis.
