As most of you know I have a 2004 that's had the face-lifted front end.

The 2004 Bi-Xenon Lights were removed.

2006 Xenon + Halogen lights were fitted.

I have just bought some 2006 Bi-Xenon + Adaptive lights, however the Xenon lens is not moving to the high beam position - it should tilt up-wards for main beam and down for dipped.

Wiring diagrams are very thin on the ground so it's difficult to verify that I have all the wires required. I appreciate the "adaptive" part wont work, so they wont swivel left/right but still thought they would dip etc.

1. Does anyone have the new shape front end withOUT adaptive lights?
2. Does anyone know whether the main/dipped control is separate to the adaptive function?
3. I would love comments from technically minded ppl on this, as to whether this is even possible or not!?

Thanks guys,

Dan 

Dan I'm no help BUT look up our new member mattstevens he has a front end conversion and has had a few light problems so may help. Try dropping Swast (Adam) a message as he's just done the conversion.
Hope it helps

I thought Matt bought the car with the Front end conversion. Still a really good shout. reading his posts he's definitely very very knowledgeable and much smarter than me!

Good recommendation, Rob.

Thanks guys - PM's & texts flying all over the place, you're all a great bunch!

Will post back if I need further assistance  

Dan, have you got photos of your previous 06MY headlights and your new ones?

From the lens side is the only difference the fitting of an extra halogen lamp in the sidelight pod?

I thought that the 06MY had three headlamp options - halogen, xenon and adaptive xenon?

Ignoring the halogens as irrelevant here, what you're in effect trying to do is go from 06MY xenon to 06MY adaptive xenon.

Both of the Xenon options have a halogen "fill in" bulb as the innermost lamp. There is only one Xenon bulb irrespective of whether it is adaptive or not. There is a shutter which changes the xenon between dip and main beam functions.

So, over and above the xenons you already had, the adaptives only add the cornering lamp (halogen) and the swivelly xenon function - no extra xenon bulb.

I don't think there's a difference between how the main beam is activated on non-adaptive and adaptive xenons, they both use shutters. Does the main beam halogen work?

Electrically, your adaptives should work as replacements for your non-adaptives, without any adaptive function - but goodness knows what position the lamps will be in. For the adaptive feature to work would require an Adaptive Lighting ECU, which sits on the high speed CAN bus and communicates to the motor control module in the lamp assemblies on a LIN bus. That plus an ignition feed and two extra grounds per lamp.

As the 04MY and 06MY headlamps have different connectors, your car must have had 06MY connectors fitted, or is there some kind of adapter harness?

So I wonder whether there are missing wires in the headlight connectors, something that doesn't make a difference for non-adaptives, but does for adaptives. Have you got a clear pic of the wide side of the connector that's there now so I can see if anything obvious is missing?

Thanks for that Martin,

There are Halogen, Xenon and Adaptive Bi-Xenon.

It's the Bi-Xenon bit I want.

Currently my Xenon bulb does not have a shutter in it, it is always dipped. So for main beam it just uses halogen. This gives a nasty yellow light on all the road signs etc. They were the cheapest lights the conversion company used.

I want dipped AND main to use the Xenon (Halogen is also used for main aswell)

As for the missing wires, the company that did the conversion left them out as they weren't needed for my poverty spec lights, not considering future upgrades, or the fact they've just ruined the night time drivability. Add that to the fact they didnt seal the plugs and all the terminals have corroded - not an A1 job, which for £1500+ I would expect! 

Your "old" lights are already Bi-Xenon - "Bi" doesn't refer to two xenon bulbs, but to the two functions of the (single) bulb (dip/main).

If you look at your new lights, they still only have a single xenon bulb

As I said, pics would be handy

I know it doesnt mean two xenon bulbs... It means that the Xenon is used for both Dipped and Main.

But the lights that have been fitted to my car only have one mode of Xenon - Dipped. It does not have an internal shutter to deflect the beam for main.

So the only "extra" light you get with main beam comes from the centre Halogen. 

I understand what you mean Dan. I used to have a '55' TD6 Vogue, and main beam was Xenon and high beam was halogen. I did, however think that Bi-Xenon was only available from either late 2006 or early 2007.
Because Xenon headlights take too long to switch on - not as instant as halogen, there's not two Xe bulbs. The shutter blocks the light, so when high beam is selected the shutter moves to allow the light through.
Because Xenon headlights have dynamic beam levelling, I wonder if a fault code would be raised if the adaptive cornering function is inactive but the beam levelling isn't?

Ah ok... well that may be how they've been wired on your RR (so the shutter is inactive), however the non-adaptive xenons are fitted with a shutter on the xenon bulb which switches them between dip and main beam in addition to the halogen "fill in" bulb.

The shutter is only active when the xenon bulb is fired up - i.e. when the lights have been switched on either manually or by the auto lights.

What you've said suggests that you didn't have an active shutter before, and as you still don't this which points to a wiring issue unrelated to the headlight assemblies themselves.

Sounds to me that you're either missing the xenon shutter feed or missing the earth for the same, or both.

Martin,

Before the conversion, my lights were Bi-Xenon, as per the Vogue spec the AB is based on.

There is NO Shutter inside my headlight, the headlight is NOT Bi-XENON.

If you look at Microcat you will see there is Halogen, Xenon and Bi-Xenon. I have Xenon only. There are also only enough connections in these headlamps for Indicators, Sidelights, Main Beam and Dipped. It is missing the pins that the shutter control signal would run.

These new lights I have have the shutter control pins, so now with the help of those above I can wire these into action. 

OK, well evidently LR have the information regarding headlights wrong on the wiring diagrams and in the workshop manual.

Night.

Evidently, either that or the whole of Microcat is wrong, and I have something in front of me that just doesnt exist! 

Here's one of those lights that doesn't exist, note the "Xenon" in the title, not "Bi-Xenon" and that microcat has it as one of the cheapest xenon headlights available....

This only has 9 pins too, which is only enough inputs for the bulbs, not enough for the shutter +&-.
