    is speed of light invariant for accelerated frames?

    Yes... in the sense that any local measurement of the speed of light gives c.

    The speed of light at some location remote from the observer depends on how co-ordinates are given for space and time.

    Note that the word "local" is crucial. Also, what sylas said assumes that we're talking about a coordinate system that the standard synchronization convention associates with the world line of a moving object. If we allow arbitrary coordinate systems, the speed of light can be anything we want it to be.
