great photos and instructions, turned out to be six clips, three up and three down on my lens covers but once I figured out how to remove the metal strip below the light, all else came out easy.
the "dirt" I had imagined inside was nothing but light coat of dust. The main culprits are pitting and dings from 15 years of use. Oh well. It was worth a shot.
thanks again for the photos and info.
