I didn't like the silver piece on top of the black background so I put on 3M Black Night reflective material over it.
During the day it looks black but at night when a headlight shines on them, it turns bright white.
I also covered mine with a 3m vinyl wrap I purchased off Amazon. Couldn't figure out how to take them off either so I just applied with it still on the vehicle. I also couldn't figure out how to get the silver piece on the hood off either so that one's still silver.
