Hank - F-150 Trucks are a little different...

On the Cobras there's an Allen wrench/Phillips screw on top of the light housing. There's probably something like that on the Lightning. Turn one way they go up. Turn the other they go down.
Actually, there are three "star" adjusters mounted on pivots on the back of each headlight bucket. These clip into the L shaped bars which hold the buckets in th truck. Lift the two brackets up (simultaneously) about 1/2" and you can pull the headlight bucket out of the front of the truck
The bars look very similar as to those what hold the Cobra's buckets in place, but are tied into the headlight adjustment unlike the Cobra.
By turning the star adjusters you move the mounting point forward or back which then make thes buckets move left, right, up or down depending on which one you adjusted. It's easy ito see how they work if you remove a bucket. Getting the buckets back in sometimes takes a little longer than taking them out as all three of the adjusters must line up pretty close to their respective holes, and they pivot easily. Remember.. patience is a virtue.
