Use bathroom fan cable for light fitting, (Ireland)

Hi All, I have an extractor fan in a bathroom that is no longer used. Can anyone advise me if I can use the power to this fan for a new light fitting I want to install? I see a positive & negative going into the fan, no earth. I assume an earth is required. If so where should the earth run to? Could it be wired up to any other earth like a socket close by?
Thanks!
Liam

 

If you are going to fit the light in the same place as the fan was then yes you can use the cable.

You will need a light that does not require an earth connection.
