These add directional information to Halo's lightmaps. Part of that means "just better" lighting, with light bouncing and accumulating more and more accurately; but the big deal is that they allow lightmaps to bring out normal maps on BSP textures.

This is a seemingly small addition with practically enormous consequences. You already know what normal mapping does with directional lighting on game objects -- allowing for the same detail on BSPs means we can bring the environents to a level of fidelity that was simply not feasible until now, at very little cost to your computer and almost no cost to our lighting process.

(For the technically minded, here's further information on what exactly is involved with this kind of tech)
