I believe this link Saids it all!

 

Maybe that s just for cars and not F150s. Aiming confuses me.

 

OK so drove around some tonight in town and country. I'm happy with aiming just under 41" @ 25 feet. My driveway slopes away from the garage the normal 2% or so, so when level, it's perfect. No one flashed me even with my fogs on and I felt ok when behind other cars. I'm sure everyone is different. I'm stock xlt no lift or level. Lights I installed were from LEDS 4x4truckleds

 

[QUOTE=Brad8899;5198433]Hello all! I just wanted to give a review on my MARK III 2015 headlight system for my 2015 f150. The light output is AMAZING, but maybe too amazing. I notice at night, about 30% of the drivers I pass head on flash there brights at me thinking I have mine on, but really I only have my low beams on. On the website it Saids that there are 6000 lumens per bulb, and that's a lot. Tonight I was behind a driver on a 1 lane road, and once it merged into a 2 lane and I passed him, he immediately turned is brights on behind me. (Guess he was a little mad) Everything about the lights are great. I just think maybe they're too bright for other people. So these are perfect, just go in knowing that you may not make some people happy![/QUOTE

I just purchased them for my 2018 and they will not pushing and turn counterclockwise at all?that’s low and high I think it’s because that was the year they went to halogen 17 and 19 they were LED I think
