if the pictures are correct, they aren't 1-piece. at that price, they are not JDM stanleys (authentic JDM headlights), they are most likely depos, which are JDM replicas. i dunno if depos are DOT approved, either..

and yes, they are just like your OEM headlights, but black housing. that's the point. trust me, they look way better than stock

probably doesn't exist. you'll just have to find something sorta similar.

i'm not sure if this is accurate, but with 1-piece headlights you might have to remove the whole headlight to change the corner bulbs...
