I started installing these lights today. I watched the F150LED youtube how to, it is pretty good. It picks up once you have removed the headlight. I did watch videos of doing it by moving the splash guard only, I recommend removing the headlight unit. I had to "clock" the collar that locks into the socket so the bulb sits correctly, not a big deal, just something not covered in any video I found.
I ordered the high and low beams as well as the marker light and fog lights.
I don't know much about LEDs but these seem like good quality.

 

Looks good to me--what LED you go with
