Slightly bigger than stock. Had to purchase longer screws for chrome bezels to fit. Adjustment screws are not long enough to adjust lights down to usable distance. Had to buy longer bolts. Lights are super bright though, literally night and day difference. Just need to include more hardware or mention it in instructions
