the two blacks to the blue neutral of the fitting, the taped red to the brown live of the fitting..... and the three reds connected together and INSULATED. ALSO ANY EARTH WIRES PRESENT MUST BE CONNECTED TOGETHER TO ENSURE CONTINUITY TO OTHER LIGHTING POINTS, THIS IS VERY IMPORTANT!!

This is s lightly better than your other question. (No idea why you did two.)

What you have is a 'loop-in' circuit. Unless you understand what that is get an electrician before you have a fire or worse.

Second in the UK it is illegal for you you carry out that work in a bathroom if you are not a 'Competent Person' (Building Regs.) or you have to have it checked by a 'Competent Person'. Doing so can also affect your chances of selling your house and/or your house insurance.
