l have been told it may be a headlight relay failure but l havent a clue what that means???Help!!!

It could be the relay, this happened to me once, simple to fix and not too expensive, get it into the garage asap (before it gets dark!)

Have you checked the actual lightbulbs?

They may just need changing.

Sell the car and get something that is not French.

Check the bulbs if they are OK its probably the relay which is located under the dashboard on the passenger side clipped on the back of a plastic box (computer). This some times comes loose/gets kicked. Hope this helps.
