I rarely ever make sense out of what he says :/
To remedy the lighting issue, I have added arrows:

There's two on the right, one on the left. Bottom tabs are for fenders/racks, which I get. So, doubting they are discs since discs always seem to be on the left (where there is only one hole). Their odd number makes me wonder if they're for anything at all, since anything you mount is going to want something matching on the other side of the bike?
