theres a light in the porch which is wired right in the supply box i want to put a outside light which is the best way to wire it off the porch light

First of all you would need to check that the original light has the right gauge of wire to carry the current of both two lights and that the original circuit is protected by a suitable fuse.

If any of the above does not make sense to you, then you should get an electrician to do it.

Second, if you are in the UK it would be an offence under Building Regs. to carry out electrical work outside if you are not a 'Competent Person'.
