One of the postulates of relativity is that is is impossible, or better stated, requires an infinite amount of energy to go as fast as light. Therefore, it is  impossible to switch to a reference frame of light. Secondly, another postulate of relativity is that the speed of light is the same in all inertial frames.    If somehow, we did manage to shift into the reference frame of light, this 
would mean that the speed of light is zero which violates the above postulate.

You are right when you say that the lorentz equations break down but that is 
because they are not designed for the above scenario.
