I just installed a 2 1/2 leveling kit. Since then, I keep getting lights flickered at me. How do you adjust the headlights. I have a 2005 F 150.

 

There is a small black hexegonal piece on the back of the light. My mechanic had the perfect ratched tool for it but a very tiny socket would work. Just use the aiming instructions online or in the manual if they are still in there. 2" drop over 20 feet IIRC.

 

you need a 4mm socket and a pair of needle nose vice grips to hold it....thats what i used

 

A crescent wrench works fine. Find a level spot, pull the truck up towards a wall 20-25 feet away. Measure the height from the ground to the little spot on the headlight. Put some black tape on the wall at that height. The focused beam of light should all be below that height on the wall. Drive around a bit and adjust from there. If you still get flashed try lowering the drivers side just a little more.
Do the same thing with the foglights if you have them.

 

Thanks for the help. I'll check it out this weekend.
