With respect mate, that's a whole other thing.



The difference between LHD and RHD headlights is not a matter of alignment, it's a matter of beam 'shape, created by the optics.



RHD dipped beam shape: \___, if you drive in the UK, on the left hand side of the road, the verge is on your left.



LHD dipped beam shape: ___/, in you drive in mainland Europe (eg) then the verge is on your right.





It's all to do with lighting up the side/edge of the road.

Thanks I had realised that.

Traditionally that is done by the optics of the outer lens. This enable the use of a lens sticker to make british car adhere to European regs.

The lens on the projector type light unit does not have any relevance on light distribution.

Therefore allowing the position and angle of the projector itself to play the part of distributing the light.

Nope, projector lenses have their beam pattern set internally within the projector lense housing. As mentioned by thebiglad what you're going on about is still different to beam pattern.

Cornering headlights moving the beam to the left of right only move the beam, they don't change the beam pattern as you go around corners.

So if we were to go over to France for a weekend, how would we correct our beam pattern?

If your saying the pattern is set internally withing the projector lens, fitting one of those lens sticker things on the outer lens wouldnt work?

In the Uk \___,

In Europe with sticker ___,

The stickers are no use, but with most projector lens headlights there is a small lever at the rear of the headlight unit - move this lever to create a flat dipped beam.

Think of it, the sticker goes over the outer housing and blocks the light, hence preventing dazzle from the kick being the wrong way. Has nothing to do with the beam pattern being created by the inner workings of a projector lens, or the reflector on a reflector headlight unit.
21dwb said that I was wrong, when I wasn't. Direction the headlight units 'point' the beam, through the leveling of a headlight is very different to the 'beam pattern' created by a headlight unit to meet LHD or RHD requirements.

Think of it like a hand held torch. I can point it in your face, or I can point it at the sky, or even point it at the ground. No matter where I point it though the beam pattern that the torch is designed to produce will be exactly the same without the torch being modified to amend this beam pattern. This is the point I'm making with 21dwb saying the projector lens points to the side slightly so must be ok for RHD. This just simply isn't the case.

Direction of light output it different to beam pattern.

yeah i fully understood what you are saying MEP.
the beam pattern is defined in the projector and moving it left or right would just skew the pattern left or right, not change the actually shape.

Thats why I showed in my pic that if you used one of those stickers, all you would do is clip the left handside that illuminates the kerb.

I stand correct, you learn something new everyday. ?

It's got nothing to do with where the projectors appear to point, it's the beam pattern than the kick it produces which defines the difference between LHD or RHD lenses.

Anyway Dont know why ther is a need for so much debate they are rhd headlights.

We still need piccies, though, once fitted -- I can then try and persuade Mrs homeward to have these on her Panda...!

If we were really cunning, we could persuade people that all 2009 Eleganza Dualogics came with these as standard...!

I'd love some for the 100HP, would make the front end look a lot more modern. Shame that in RHD they make hen's teeth look common.

tell me u r kidding, ther was me hoping no scratch that actually depending on your approval over anyone else what am I gonna do now u dont like and approve of them change your mind please please please please

I can see a lot of people going for them but they are not for me i'm afraid, if they did them without the fairy lights i'd like them a lot more.

Yep, I'm with Gav on this... the lights are lame!

Thats why I went ahead and made my own!

:yeahthat:But without the indicator led's ...I can appreciate the skills but I just don't like bling in any shape or form.
