Have to say, coming from a world of nineties headlights (various German marks) the difference in brightness is huge, guessing these are early xenon bulbs but in the scheme of things, on high beam especially, it’s a bigger improvement than I was expecting. Are L322’s known for good lighting of the road or is it merely the fact that my starting point is so vintage? My wife’s 09 civic isn’t too bad to be fair but the height, width and travel of the headlights on full beam surprised me. 2009 pre-facelift 3.6 TDV8.

Have you checked if your fill-in bulbs are still halogens?

Also bear in mind the seating position is very different, you can see more of the road & surroundings in a Range Rover, the average seating position in a German car is the equivalent of dragging your arrse along the ground like a dog with worms...

Looking at my lights I take it the main beam is xenon and the side lights are standard halogen, the high beam I am guessing is a very bright halogen bulb or is that also xenon? Is this generally the same set up on all 2007-2009 cars?

The Halogens are high-beam fill in to supplement the Bi-Xenons which are both dip & high beam by virtue of a movable shutter - see my 'HiD or LED' thread for info on upgrading the high beam halogens. The side lights (tungsten 'wedge' type) are in the lower outermost corner with the 35W Halogen 'cornering' fill-in lamps.

Ah ok thanks. So high beam is produced by both main lenses but primarily from the xenon. May explain why it’s so effective. Can’t imagine how bright the latest led lights are on high beam in the new Range Rovers. 2009 pre-facelift 3.6 TDV8.

Your fill-ins are still factory-style halogen globes. I replaced those in my MY12 with an HID kit which rather dramatically improved light output.

Know there will be some dedicated threads on this but a simple question for now - is there wiring work to do or is the HID kit quite plug and play? As you can tell I’m quite happy with what I have but always happy to improve things. 2009 pre-facelift 3.6 TDV8.

The HiD's I've been experimenting with have 'just worked', LED's on pre-2010 MY are problematic.
There is more involved with getting the electronics into the headlight assembly with the HiD's but it's not by any means difficult.
I'm intending to re-align the high beam fill-in reflectors but it's by no means a 'must do'.

Thanks. Think I’ll stick to what I have as the novelty of seeing where I am going is enough for now! 2009 pre-facelift 3.6 TDV8.

Hello together,

L322 Bi-Xenon Lamp

Low-Beam and High Beam = 35W D3S Xenon-Bulb (Mechanical shutter and Projection System)

additional High Beam Spot = Bulb (Bulb and Reflection System)

All 35W Xenon are required to have a Outer Lens Washing System, for the 25W Xenon Systems it is not necessary.

Also all 35W Xenon require a automated Leveling. This is done via a manual stepper engine in the headlamp.
The heigh measurements for the HL are generated by the body leveling sensors of the car (same as in for the ESP System).

For the higher performant LED ADB ("Matrix") Systems nowadays, there is also a leveling by stepper engine needed - at the moment same systematic as for the 35 Xenon. Current:
- 2006 RR L322 - 3.6 TDV8
- 2022 MB AMG GT BS
- 2020 Audi Q2

Past:
- Ferrari California 30
- 2018 Abarth 595 Competizione
- 2009 Porsche Cayenne Diesel
- 2010 MB E500 Coupé
- 2005 Porsche 996 Turbo
- 2002 Porsche Boxster 986 S
- 2001 Audi S8

Thanks for the above. 2009 pre-facelift 3.6 TDV8.
