failed not for beam...advice needed.

maybe get lights readjusted or get brighter bulbs.

I know that for cars coming from the continent, the headlights need to be replaced. Left hand drive cars have more or less straight beams unto the road whereas cars in the UK and Ireland have the right hand beam deflected toward the kerb. This is why you need beam deflectors when going to the continent to straighten the beam and cut out that deflection which would be pointing at oncoming drivers.

Unfortunately beam deflectors will not work to create this angled beam which is why headlight units will need to be replaced. They are specially made to UK spec. Once fitted they will also need to have their alignment set properly. It is the one common modification needed if buying a left hand drive car. I would assume that motorhomes would need to comply with the same law regarding light beams.

It also means that if you go back to the continent, you will need to apply beam deflectors.

And that's completely inaccurate about LHd European cars not angling the lights. They do. I've set enough lamps on the beam setter to be sure. American lamps afaik don't angle.

Our previous Motorhome, based on LHD Ducato, passed its test everytime with Beam benders, you need the ones for Lhd vehicles ,not the ones you buy here for going to the Continent with RHD vehicles. I got them on ebay Germany if I think correctly.

thanks tristan. it was a test centre in Donegal, it just said failed dip beam and it was due to lhd lights. the van passed last 3 tests down ur area, they said regs changed in jan 2015? ill try a new set of beam deflectors and see!

If you have upgraded the bulbs since the last tests that could be the problem. some of the modern bulbs don't give the correct beam pattern through old headlamps?

Did you not make that known to them and ask them why they failed it this time?
