A mobile apparatus is provided for measuring photometric characteristics of airport marker lights. The mobile apparatus includes a measuring rod configured to be moved above the marker lights to be checked, in light beams emitted by these marker lights, and a device for measuring the distance between the measuring rod and the marker lights to be checked. The measuring rod carries at least one photometric sensor and includes a device for acquiring and processing the signals emitted by the photometric sensor or sensors during its movement, as a function of the distance measured between the measuring rod and the marker lights to be checked. The device for acquisition and processing is configured to generate a set of data representing photometric characteristics of each marker light checked.
