Thread: D4 high-beam alignment

On the contrary, LGM has described a different problem to the "possum spotter" halogen beams discussed in the bulk of this thread.

LGM's problem is described as "the centre part of the high beam" being set too high. The centre part of the high beam is the main HID beam (ie, the spot beam straight down the middle of the road), which has not really been discussed as a problem in this thread.

Adjusting the lights downwards will bring that main beam down and should fix the problem described in this post. Whether or not there is a separate problem with the adjustment of halogen fill-in beam on these particular lights is not yet clear, as that was not described in the post.

Best to try the simplest solution first, but I'm curious about what the dealer will say.

Like I said, the lights on high beam are 'different'! They certainly put out a spread of light both left and right towards the tree tops but they also have a spread in the forward direction along the road albeit poor. Hence my thoughts on a good set of driving lights.

I was not planning on getting to the dealer anytime soon (400km) so my discussion with them will have to wait, as will the driving lights until my (ordered) bull bar rolls up.

None the less I do believe the lights are not as they should be and its the dealers / LR role to fix same.

I live in hope!

Halogens come on with the high beam so the issue could be either. If the main lights are too high then adjustment may be the answer and could bring the holagens into line too.

Thinking of our soldiers, fallen, returned, former and serving on this Anzac Day.

My latest and possibly last post on this issue. After speaking with the service manager and foreman technician at my dealership yesterday, there is no fix for the possum lights because for some unknown reason, that's the way they were designed. The shallow, wide fill-in halogen beam is apparently designed to be positioned immediately above the central beam of the bi-xenon lights. The reason for this is unknown and Land Rover is not telling. It is still not clear what the halogen beam is meant to fill in. So I guess we will just have to suck it up and live with it but at the same time warn as many potential new customers as possible that this is the case and they won't get any joy from LRA. It would have been nice if LRA got their PR mob to issue some sort of positive statement instead of going on the defensive. All we expect from any corporation we deal with is for the issue to be fixed or information why the issue is so.

Cheers, beers and safe driving.

I stopped beating my head against LR's brick wall some time ago. My tilted 3000K 55w HID globes broaden the beam sufficiently to bring the lower edge low enough to be about where it should have always been and still produce enough light even though the top of the beam is still way up in the trees. 5500K globes would produce more light if needed.

As discussed in my earlier posts, my answer has been to install a good set of driving lights. At that time I was waiting on a bull bar installation. I now have the bull bar and a set of HID driving lights so I have, to a great extent, solved the problem that I should not have had in the first place.

I have also had similar comments about the lights from the selling dealer and did not see any benefit in labouring the point. After all its not their fault. I will be in the UK this August and am taking the opportunity to visit Solihull taking the factory tour and an afternoon on the test track.

I am certainly lining up my questions!

Maybe it is a long shot that someone in that environment will be able to 'throw some light' (no pun intended) on the subject.

I understand the need for self-preservation when the LR brick wall proves harder than your head, but this story about "designed that way" is obviously wrong. If they were designed that way, all the D4 headlights would have the same problem, but they don't. There are plenty (the majority?) that don't point the halogen spread beam into the treetops. For example, gghaggis commented in this thread (3 Feb 2011) that he had no problem with his and implied there were others who had no issue with their lights and didn't want the hassle of a recall.

Having said that, I also took the soft option some time ago and replaced the errant beams with angled HIDs, much better outcome and my skull is almost back to its normal shape.

Cheers.

Not that i can remeber all 200 plus posts, but it seems only a few people have this problem. A few too many maybe, so it should be quite obvious to LR that there may be reason to allow owners to have an alignment check with possible replacement. Wouldn't need a full recall surely?
Could it be possible there may have been a bad batch of lights manufactured?
Has anyone with a MY12 got this issue?
When it's time, I might take an additional test drive at night!
In line with the rest of the vehicles credibility, i would expect nothing but the best when it comes to lighting.
