A very common problem on french cars.Take a close look at the connector pins and you will probably find one or more of the pins in the plug has overheated and/or distorted.It is usually the common earth to all the bulbs.Easiest solution is to locate the earth track on the bulbholder assy and run an additional wire from this to the earth wire on the multi plug of the wiring harness.Also make sure the pins on the lamp are in good condition.hth
