In [[Theory of relativity|relativity]], '''light-cone coordinates''' is a special coordinate system where two of the coordinates, x<sup>+</sup> and x<sup>-</sup> are [[null]]{{dn|date=May 2012}} coordinates and all the other coordinates are spatial. Call them <math>x_\perp</math>.
Assume we're working with a (d,1) Lorentzian signature.
