Good product, good price
Came with bulbs installed for high and low beam....one height adjuster was broken and they sent me a new one immediately.

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. That's 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...
