Currently based in the UK, but moving to Denmark next month. Because I will need to have Danish plates and insurance on my current car, Mazda 5 2007 model, I need to change my headlight units from RHD to LHD units.

Questions I have:
What is the part numbers for the headlight units? as I cannot find it anywhere.

Are any of the headlight units universal? i.e. will the Mazda 6 headlights fit on the Mazda 5.

Where can I buy the headlights? The cheaper the better!

Any help will be much appreciated
