Arrived very quickly, packed perfectly, fit perfectly. These headlights appear to be high-quality, and the bulbs are included also, that will save you at least $40. You most likely will need to adjust the beam at night. However, you can buy the tool at O’Reillys for $10. Ford makes a specialty tool for this headlight adjustment. It’s a very long, skinny, 4 mm socket used to adjust the headlight beams. Was very easy to install and adjust. I recommend these headlights if you need replacements. Also got the side markers which also fit perfectly.

Still clear
Have had them installed on car for over 2 years now, and they're still clear as the day I got them. Bulbs work great as well. I live in Florida, the state known to fog up headlights.

What is the headlight assembly sealed with? Butyll or perma seal?
Michael V on Aug 6, 2017
BEST ANSWER: I'm not sure what they are sealed with but I've had them for almost a year and have had NO problem with them at all. Great buy because I've spent over $200 in the past years trying to clean my lights, so spending $100 for a full set of new ones was a no brainer.. You wont be sorry
