Thread: D4 high-beam alignment

My dealer yesterday confirmed that the original D4 light part numbers have been superceded, but needed to check if the replacement ones mine received were the old or new part number. I have the documentation from the replacement lights and the lights are the old numbers. Google has been useful in finding the replacement part numbers so I'll be pressing the dealer to obtain a set of the new part numbers in case they're better.

Edit: Looking into the headlights of 2 new RRSs & Freelander, the halogen globes seem to be parallel to the bi-xenon assemblies but a new D4's halogens seemed to still slope downwards. Maybe the part number on a D4 light assembly can be checked to see if its the old or new number and the light checked against a wall if its the new number.

I just took some photos of my June 2011 Build(August compliance) D4 SE Halogens Graeme. See if these help so far. I have found the lights to be ok generally. I reckon the high beam actual globe seems straight/parallel/horizontal. The surround is tapered so could give an optical illusion of pointing down maybe???

Regards,

Les.

Thanks Les.

The halogen globe doesn't seem to be pointing down the way mine did before fitting HID globes on an angle. If you have you pointed your lights at a high wall at more than about 20 metres away you would surely know if you had the possum lights.

The sticker with the part number is on the top of the assembly and quite visible with the bonnet open - on mine's original and replacement lights anyway. It would be useful if you could at some time have a look to see if the left light has part number LR013989 or LR023540 or the right light has LR013973 or LR023539, with the 2nd number for the superceding parts. My original lights had totally different numbers which look like production numbers rather than the normal part numbers above.

Edit: I didn't even look at your 1st 2 pictures that show the labels that are the same sort of number as my originals, but I will go and check those numbers now.

Edit 2: Same top numbers except that the suffix is FC on both lights, suggesting your assemblies are a modified version. The bottom numbers could be batch numbers.

Lucky I didn't hold my breath. Just found out LRA refused the order from my dealer weeks ago and didn't tell me. Don't know why at this stage.

I suspect my dealer wont even try as the report is that new vehicles are still the same.

Hi Les,
Any chance of getting pictures of the lights on both low and high beam shining on a wall from about 20 metres?

FWIW, I have a 11MY D4 2.7 and it not only has the "possum light" feature, but also found out (on the way to the AULRO 10th) the HID low beam flickers when I hit a pot hole. It is like the whole light assembly is loose.

So I will have this looked at during 1st service.

I'll try to at some point - need to find a suitable factory wall too!
I'm sure they could do with a little adjusting anyway, especially the driver's side points a fair bit left.

Les.
