Cleared up my lights today. Wet sanded, polishing compound, and Meguiar's headlight protectant. Not perfect, but better. The faint inner cracks are still there from my aftermarket HIDs running hot, but they're inside the housing and not posing any imminent threat. I investigated and I can't feel them at all. In fact, the lenses are as smooth as glass now! And yes, the HIDs have been removed.
