Check your owners manual to make sure this is not normal for your car, otherwise it may be a sticky headlight relay.

Thanks for your help. I can confirm that it is not normal. I have driven the car for over a year now without such problem. I just noticed that about a week now.
I will like to check the relay but where can I find the headlight relay in the car please?

On inspecting the wiring schematic, the relays are in built into the SAM module, this will have to be checked by a dealer
