Bed light

[DIYMIKE]

Can someone help me please. I want to wire a bed light above my bed and lose the cables in the wall and have a string pully to switch the light on/off. I'm assuming the cable goes up to the ceiling and is wired to the ceiling rose providing light to the bedroom. This rose has 4 wires going into it. One to the switch, one to the lamp and one in and one out of the lighting ring.
Can I spur from this rose to the new light? if so where do the 3 wires attach to? and if not how does it work?

[img]http://www.ericmark.talktalk.net/lights.bmp[/img] the linked picture shows how they are connected that's if the admin permit the link. The two three terminal connectors in the ceiling rose have power all the time the two terminal one is switched.
There are many ways to wire. I have two double intermediate switches at bed head one each side and a triple two way switch at the door. Three lights one centre of room and two either side of bed.
From the door I can work all lamps. From bed lamp that side and main lamp.
I have diagrams at http://www.ericmark.talktalk.net/twoway.html but the pictures are BMP and this site will not allow that format.
However in the Projects section there is a lot of information.
