I want to change the light fitting in my downstairs toilet, i've done several other lights in the house but i've become stuck on this one. all the other lights have been 3 wires (L,N,E) and have been an easy change. however i've now come across a 4th wire in the toilet. it's got a green, a black and a red wire but also a black wire with red tape on it. the connector in the new light fitting is just for the 3, which is the same for some other lights i fitted? I'm not sure what the 4th wire is, can anyone help with what it is and i need to do with it. TIA
4 cables into 3 on a light fitting?

It's likely all the reds go together on their own in a seperate connector block which you may need to provide yourself.
The black with the red sleeve is the L to the light.
The remaining blacks are the N to the light.
The greens are EARTH, and need to be connected together - use the earfth terminal on the light if there is one. A metal light needs connecting to earth.

EDIT, it sounds like you have ONE CABLE with 4 WIRES, after re-reading. If so ignore all above. A photograph maybe useful before you do anything.
The thing to remember is all you are doing is replicating how it's already wired. You need to copy how it's wired to the new fitting, which may include having to fit an additional connector block.
Pictures or a better description may help here.
