I have an LH drive Roomster in Ireland. The last NCT (a.k.a. MOT, TÜV, APK, etc.) failed on both lights "dipping to the right". I have 2 corrective Fresnel lenses on the headlights, which got me through last year.

Can I replace the headlights with the headlights of an RH drive Roomster for a more permanent solution?

Headlamps are interchangeable, no CANBUS issues etc. However, if you happen to have projector (round lens) headlamps, they have a lever inside the dipped beam opening to switch from dipped beam to true flat beam. If you have those on the car, It may be worth asking MOT tester whether they will pass the MOT on the flat beam setting. Until 3 or 4 years back, they would pass in England, not anymore, but I know that even NI has a slightly different test rules. Road lighting is very good on flat beam, still my favourite beam shape for trips abroad, sadly unavailable on newer cars.

Thanks for the tip! I found the levers, and I will ask the NCT if this configuration is allowed in the Republic of Ireland. If not, I will glue on 2 new "beam benders" and hunt for RH headlights. These seem to be about 55 E on eBay.

Applus (the company that does the testing in the Republic of Ireland) confirmed that the flat beam configuration is allowed. I had it tested at the local garage, just to check, and it passed the MOT.
