The Paul Girardin Frères establishments (PGF), were a major Parisian public lighting manufacturer. Their lanterns notably equip the Place de la Bastille, or the forecourt of the Eiffel Tower.
On the strength of this success, Girardin has also designed the famous cast iron repeaters used throughout Paris, with incandescent lamps, fluorescent tubes, or LEDs, as well as a model of illuminated push button and a pedestrian signal that are more rarely encountered.
Girardin's traffic light activity ceased in 2004, the year Grolleau took over the Paris traffic lights market. The company was renamed Girardin Lighting and is still active today in the field of public lighting.
