Just want to know if anyone has any idea's what may be the problem . Thanks ,

Not helping you much, but you likely have some wiring damage. You need a multimeter and a wire diagram. First, do a good visual inspection of the wiring at and around the headlights, parking lights and throughout the engine bay. Removing and cleaning the electrical ground points is also something you should do.

BTW, what does N/S stand for?

I think N/S would be "near side", drivers or right hand in the UK.

Are the license lights on that circuit by chance? A fault there or in the umbilical to the hatch is quite common.

Short to ground somewhere is likely, the problem is finding it. Chafed wiring/broken insulation is what to look for. License lights easily short to ground if loose.

You are making it difficult for us to help you. Please help me with more precise descriptions of which lights are not working.

When the 10 amp fuse is OK and the 7.5 amp fuse is blown, which lights are not working?-> Parking lights on left side only -or- all parking lights?

Also, N/S was a typo? So, N/S should have been L/S for "left side" correct?

I just looked at a 2003 wire diagram and now see the L/H and R/H separation. My newer diagram might be off/mis-lead you some because of the age and model differences.

R/H has one fuse (F57); L/H has a different fuse (F58).

Now that my brain is less confused, you need to visually track down the problem or use a multimeter to identify where the fault is. Please visually check the wiring health at each light bulb socket, front left & back left.

Also remove and clean-up the ground connection (G37) for the front left headlight located inside the engine bay, likely located inside engine bay and next to the (UK) passenger side wheel well.
