The second is an innovation of Grant Morrison's, and plays to the idea of the symbol's visibility: it can be illuminated as Batman goes into an attack, letting his prey know exactly who it is they are dealing with.
This is why I love the oval. Batman works in the dark, but the yellow oval can be seen clearly by a crook.
