Headlamps RHD LHD
Slimer:
Manual only mentions the switch for Xenons so I presume Halogens are sticker job
petergalileo:
Well I will check them out when they arrive, thanks for the info.
petergalileo:
Well lights have arrived, they turned out to be UK ones anyway !
However, crikey they are absolutely gigantic ! I shall be investigating the possibility of fitting them to the disco 1 but I doubt its possible without a whole load of welding !

--- Quote from: "Slimer" ---Are they definitely Xenon ones? Some models come with Halogens
Assuming they are Xenons and you sort out the other issues there is a switch inside to convert them for LHD or RHD. This might be true for Halogen ones too

No don't start confusing the issue.. Zenon is a halogen, it is used in modern bulbs (whether you pay extra or not :wink: ) instead of Iodine which was the common halogen untill recently./
HID is the new gas discharge sytem that high-end cars like BMW and Range Rover have, it works like a strip lamp but requires IIRC 90v to work properly so on a 12v car you need a box of trick to step the voltage up, this is not normally part of the lamp.
Don't know about the C&U stuff for these but the 'self' leveler? do you mean hight-adjustable headlamps, operable from the driver's seat. I can understand why this is necessary but I can't imagine it would be automatic.

--- Quote from: "petergalileo" ---well at the end of the day, even an HID bulb works the same as any other bulb surely.

No.. completely different..
The 'D' in HID stands for 'Discharge'... that's a brightly burning Arc in the glass envelope and needs high voltages to operate. Hence the need for a starter and ballast.
A 'normal' lamp is incandescent... i.e. a bit of wire gets hot and glows. and just needs sufficent current to get hot enough.
If you connect 12V to the HID lamp... it won't do much at all.
