These are a pair of headlights that haven’t been installed but are missing one of the rear circular caps that cover the access to the headlight bulb. The manufacturer sent new ones to replace them but never required these in return. I found a replacement cap for it from another headlight assembly and it is included so the unit is properly able to be sealed from the elements. This is why the discounted price. The lights have NOT been installed or used. ***They have been Tested and work. They come with bulbs, H1 high beams and H7 low beams both halogen. Unit can be upgraded to LED plug and play versions of those bulbs easily. DRL lights are white while running and when using your turn signal they turn from white to amber.
