Price was right.. fit perfectly BUT
So I would be THRILLED with these items except for the following two issues 1 - There were NO instructions on how to adjust the headlight beams Up/down. 2- trying to wiggle the unit so that the holes align and the guide pins fall into place actually was enough to break the black plastic cradle inside the unit in half. I had to crazy glue it back together. Thats really bad in my opinion because it REQUIRES that you wiggle it until the pin falls into place.. 3-The plastic retaining ring that holds the headlight bulb in place was not attached and was clearly defective.. again crazy glue to the rescue...

Glad I pulled teh trigger on these!
I had ordered a les expensive set; however once they arrived I knew I had mad a mistake by trying to do it on the cheap. I sent those back and ordered these as my next try. No need for a 3rd try. These are as close to factory as one can get, installed easily, and adjusted easily. I do not think they adjust the bulbs at all as mine were aimed right at the ground when installed.... even but right at the ground. The adjustment screws made it very easy to put the beams where I wanted them in less than a minute. Good buy and they look great!
