Well, does the label specifically say Trek bikes, or just bikes? If it says "bikes," then you're good.
FWIW, I know Trek makes good bicycles and I ride one myself. In terms of how good their accessories are, I have limited experience but at the very least they aren't really renowed at them. (I know of no Trek accessory that's gotten rave reviews here.) I had a 1 LED white light from them years ago that brke before too long. My cyclocomputer from them is OK, but the magnet holder requires some babying to properly secure to the spoke. Top-rated lock companies are Abus, OnGuard, and Kryptonite.
