Are my 2012 autobiography headlights bi xenon, ? And does that mean full beam is xenon ? Just getting confused reading threads about upgrading them, also the side light LED,s in the circle can they be changed ? And which fog light bulbs would get rid of that yellow look ? Thanks berty

Yep, bi-xenon meaning a dual beam xenon projector, but there are also additional halogen main beams.

For "whiter" bulbs (fog and main beam infill), take a look here: http://www.disco3.co.uk/forum/topic142054.html Be quick if you want some, because I'm looking to put the first order through tomorrow if possible.  Visiting from DISCO3.CO.UK

So what would I need to improve my full beam, and make my fogs whiter?? And how involved is the fitting, will it cause any issues, I've heard a few aftermarket bulbs cause warning light to come on, also can I change the side light bulbs I like this look, thanks berty

LEDs for fogs. Whiter than a white thing :-

Sidelights are built in so not changeable. You'd need a pair of H7s for the main beam and H11s for the fogs (the Xtreme Whites would be what you're after). As high quality bulbs drawing standard wattage, they shouldn't cause any issues (fully legal also). Others will be able to advise better as regards fitting (I'm not a FF owner).

LEDs as above wouldn't give a fog beam, though there are those available that do, at a cost.

Right on investigation of my yellow main beam headlights it would seem there a halogen build so how is that a bi xenon headlight ? I always thought bi xenon meant xenon full and dipped, is this another money making spec change by Landrover or has my car had a bump at some point :unsure:

See my PM - if they're adaptive, they are xenon, but they still have an additional halogen bulb.  Visiting from DISCO3.CO.UK
