Disco 4 Aftermarket Xenon Lights installation

Kev,
The high beam power wire powers the shutter and the high beam fill-in globe in the bi-xenon assembly or the just the high beam globe in the halogen assembly. There is not a separate wire for the shutter.

It could be that when the CCF is set to bi-xenon that a higher initial current draw is considered acceptable whilst not acceptable for halogens or possibly for bi-xenons the power is pulsed very quickly for a very brief moment to make the globes start-up more quickly, or for some other reason that I can't think of.

Removing and replacing the headlight assemblies is very simple and quick once you know how to remove the grille and release the 2 headlight assembly retaining catches.

A dealer may not be able to change the setting with their equipment as LR bundle certain features into a market package but non-LR equipment will change the setting. My Faultmate is keyed to mine's VIN so wont work on your vehicle but an unlocked device owned by a LR specialist workshop would. If your dealer can change just that setting then that's all that's needed. I would be getting the settings changed in both vehicles after doing the swap.

In your situation you might need to consider the possible reduced salebility of an earlier SE fitted with halogens when they were fitted with bi-xenons and a buyer might be upset if they bought the vehicle only to discover later that the good headlights had been removed. Perhaps you might consider getting a s/h set from the UK for your new vehicle.

Edit: CCF - Car Configuration File. It is referenced by the various ecus when they need to know if a feature is fitted so that different actions can be taken for different options or the actual specifications of a feature, eg tyre rolling radius to allow the ABS sensor signals to be converted to a speed signal (RRS have approx 29" tyres whereas Discos have approx 30" tyres). The CCF also has build information that is just notational and not used by any system, eg towball fitted/not fitted.

The car is self leveling so meets this requirement - the optional Bi Xenons in the D3/D4/RRS are not self leveling as the car does this.

[Holmes] - Dr Watson this theory sounds suspiciously incorrect !
[Watson] - Why, What do you mean Holmes ?
[Holmes] - According to pg 36 of the LR manual, it clearly depicts a Height lamp adjuster for the main lamps. It's a dial that lets you adjust the vertical focus of the lamps
[Watson] - What ! they are not automatic ! How dare they ...... Manual adjustment....

[Holmes] Perhaps this is a misprint, you know this is a foreign manual
[Watson] Yes, yes ... written in some foreign language by foreigners - what do they know
[Holmes] We need to investigate further. Quick smart Watson, don't dally...Come on man... Move on...
[Watson] Coming, coming..

Once adjusted correctly the headlights will remain level regardless of the load in the rear because the suspension keeps the whole vehicle level.

The adaptive headlights, also bi-xenon, keep the headlights level when accelerating and braking and also turn left or right when the steering wheel is turned left or right but are still required to be adjusted correctly initially.

That's for coils sprung vehicles, which we no longer get.

Air suspension is self levelling.

Cheers,

I will check with the RTA, technical support - Will post what I find out.

Holmes is very suspicious, He thinks someone may be arguing a point of view rather than a fact !

I wouldn't waste your time.

If that's a point of view and not a fact, then mine and every other Disco 3 & 4 sold in Australia with bi-xenons and air suspension is unroadworthy.

Exactly. LR have been selling them in Aus for 8 years. Someone would have twigged by now you would have thought.

What outcome are you hoping to achieve? If you think that headlight levelling using the suspension isn't accurate enough then you need to do some night driving on low beam on a dark street which will confirm that the low-beam cut-off doesn't change regardless of the load in the vehicle.

That's not what I meant - surely your model LR would have a mechanism for self leveling? I don't know. Does it ?

I am more interested on the requirements for after manufacturer modifications, as mine has halogen.

Good suggestion, I am surprise to find out that the higher models don't have anything special for auto leveling.

Cheers Graeme.
