It was my sister's car and has done 25 thousand miles, I would like to take it to France in June, so the question is how to change the headlights from left to right hand dip ?
Why? If you are just visiting in France, you don't need to do anything to lights!
If you are moving to France, ask about their laws, rules & MOT procedures!
By buying used or new right hand dip headlights, from Germany, France, Spain, Italy etc.!
Where people normally drive on '
right' side of the roads!
You might find continental Europe headlights also from UK, fairly cheap...
