With the F150LEDs MKIII headlight system, you can adjust the light cast by using our bulb rotation feature.
There is no 'right' way to set the headlights. It is based on your preference, your trucks stance, etc etc. How we send the lights is what we like best, but feel free to modify if you think they are causing glare to other drivers etc.
Please Note Aiming the headlights correctly using the trucks headlight adjustment screw is very important in getting the most from your headlight output and preventing discomfort to oncoming drivers.
On a pre-2015 MKIII headlight bulb, to manage the light cast you can simply rotate the unit. To do this, remove the Allen screw, rotate the headlight to the desired location and re-install the Allen screw.
For a 2015+ MKIII bulb, the operation is the same. Below is an example of the screw location.
