The first set came with a broken headlights adjuster, but everything else worked as intended, Amazon replaced it in a timely fashion and I'm in love with the way they look and the quality of lighting, have gotten alot of compliments already as they are on a black car and they really do give it a more aggressive yet sleek look. The plugins fit snug and lock as they should, how ever it would have been nice if connectors would have been included as to not have to cut my oem wiring. All in all this was a pretty easy upgrade to do myself, plenty of YouTube vids to aid you if your less mechanally inclined then myself. Also they purchase price was cheaper then buying oem replacements to boot!
