OK I know it is minor, but the silver screws in my front BD OnX6 light were bothering me as well. Took longer to find these screws in black anodized aluminum. First place I ordered from sent me steel screws. One of them was black oxidized and the rest were dipped or painted.....at least they gave me all my $ back and let me keep the screws.
