D4 high-beam alignment

Okay - so took the Disco into the local dealer today as requested, and gave the technician (funny how they're not mechanics any more!) the full rundown on the issue. Not surprisingly, he rang back an hour later saying "well, according to our test machinery the lights are set up perfectly..."

To his credit he was happy to acknowledge that this meant little in real terms. He did however confirm that to the best of his knowledge there is no way of adjusting the halogens separately to the bi-xenons. He has sent what he calls a technical bulletin to LR Australia asking about this, and I should know the result of that process tomorrow. Will post again once I've heard something.

Thanks for all your info, Caver - appreciate the effort to help out. Graeme - maybe we need to see if we can flush out more owners with this issue, and get lots of tech bulletins going in to LRA. I wouldn't bet on it making a huge difference, but it might just prompt something positive.

I can't just drop into my dealership as its 5-6 hrs away but I have asked my contact if he/they can check-out another D4 that has the standard bi-xenons. I'll post what feedback I get.

Perfect excuse for a front bar and some spots....... :D

Exactly! Have already ordered ARB bar, though it seems this might still be months away due to all the compliance process they have to go through. And the Lightforce's are sitting in a box, awaiting something to be mounted on. Till then at least I know I won't hit too many possums - roos I'm not so confident about!:)

I've made temporary L brackets that bolt to existing brackets behind the grill and poke out through the grill for my old HID-converted Narva 4x4 lights. They look a bit odd not mounted to a bar and with their old battered plastic protectors, but at least I can watch the roos as they jump out rather than just watch possums.

Sounds like a job for next week, when I may have a little more time. Question: did you do your own wiring? Local auto electrician? I had a brief yak with service dude at dealer re this, and there was all kinds of muttering about "complicated wiring system... got to get it right... warranty issues if not to LR specs..." - and of course mention of large sums of money to have it done by them. Suspect this is a garden path I don't need to wander up?

LR method required money to the dealer to enable. Taking a switch wire off the halogens to the relays would be simpler and cheaper.

Same here - just transferred my D2 setup to the D4. I installed a press button switch in the left side of the lower steering column cover where there's an outline just right for a switch position.

As an aside, I was having trouble finding good places to mount the HID ballasts, so just glued them under the front of the top panel behind the grill using construction adhesive.

Just a quick follow up on this matter: LR Australia responded to my dealer's inquiry about the halogens and their adjustment, saying: "sorry, lighting as-is is an attribute of the car. And no, halogens cannot be adjusted independently of bi-xenons". Seems there are a few in the UK raising similar concerns - for those who haven't already spotted it (forgive the rather poor pun!), see:

That is a disgusting reply from LR Austalia. LR need to find a solution.

If the Halogen lights are not pointing in their right direction (ie to light the road at a distance) then they have a design fault. Claim that the halogen lights are not fit for purpose if they cannot be adjusted. The halogens (and the whole light cluster need to be in the right position first before others are adjusted. If they are not then the vehicle is not suitable when supplied.

Cover the zenons and put on hight beam. Place can a good distance from a light coloured wall. Take photo and send to LR demanding a solution.

PS post it so we can see.
