1. Wash and Dry headlights and tape of the surrounding area
2. Wetsand with 2000 grit sandpaper and a sander-block, rinse
3. Wetsand with 3000 grit sandpaper and a sander-block, rinse
4. When completely dry, machine polish with a compound followed by a finishing polish
5. Clean with IPA
6. Protect with Opti-Lens, 2-3 coats of sealant (let each coat cure before applying the next one), or place some clear protective film

Protecting the lens after correcting them is important in preventing further oxidation or yellowing since the sanding will sand off the factory protectant.

I would do a test spot first, it'll depend on how deep those cracks are and if they're on the outside surface or the inside.
Thanks a lot!
I actually had to do 1200, 2500 and 3500 grit followed by a 3-step polishing followed by sealant.
Got everything from Chemicalguys(dot)com
Spent Saturday afternoon on it.
