Could someone please tell me what bulbs i need, I am looking at the Osram night breaker unlimited, I think they are H7 if so how many do i need and which bulbs do i need to replace the side and reversing light

Thanks Steve

H7 is the headlight main beam fill-in bulb. Sidelights are 501 W5W. Reversing lights are 382 I think. You need two of each.

Look at Advanced Factors in the sponsors area  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Thanks for the reply, so do I need 4 H7 bulbs 2 for the headlights and 2 for the full beam, Thanks Steve

If you have Halogens, yes.
Here's a list of bulbs from the Owners Manual

 ON THE WAY: BMW F21 M140i
MERCEDES GL350 - Metallic Navy Blue w/Grey interior

GOING: BMW F31 335D MSport+ xDrive Touring
GONE: Land Rover Discovery 4 HSE - Stornaway Grey w/Black Interior (wish we'd kept it )
GONE: BMW F10 520D MSport - Carbon Black
GONE:MY12 RRS SDV6 HSE Sumatra/Ivory/Grand Black Privacy glass

Do not trust the manual on headlight bulbs, check what you actually have. '08 RRS TDV8
I converted my diesel RRS to run on an environmentally friendly mixture of caribou fat and baby seals oil

Thanks, This might sound daft but will mine be halogens i have a 2008 RRs

Probably a stupid question but can you buy zenon H7 bulbs and replace the H7 Halogens? I dont even know what I have to be honest.

And can anybody recommend a brand/type?

Thanks

You can fit H7 bulbs that use Xenon gas to produce more light but these are not the same as an HID system which requires ballasts to create a higher voltage etc. An HID system operates by creating an electric arc rather than a filament. There are good HID kits available, and plenty of bad ones, but none are road legal. A decent, well fitted kit should not cause undue glare to drivers but it is still not legal.  Visiting from DISCO3.CO.UK

worth replacing the reversing with LED's from Advanced Factors IMO  ON THE WAY: BMW F21 M140i

Ok but say I have the H7/11 Halogen bulbs, can i then opt to use these xenon bulbs instead?

While, I think, you might be able to get the D2S bulb to fit in an H7 with an adapter, you would have to ensure the arc remains at the focal point of the reflector. The slightest change (even just 1mm) has a dramatic effect on the light output. You would also have to purchase ballasts and wire them in or the bulbs would not function. In short, you could not just replace the H7s with those.

If you don't have the xenon lights, the best bet is just to swap the units.

If you really want to upgrade your halogen main beam, this is a proper H7 conversion kit containing what you need: http://www.hids4u.co.uk/h7-55w-pro-max-xen...n-kit.html
