Locate the vertical adjuster on each headlamp. Use a number 2 Phillips screwdriver to turn the adjuster either counterclockwise or clockwise in order to adjust the vertical aim of the headlamp. The upper edge of the light pattern should touch the horizontal reference line. 6. Repeat Steps 3-5 for the other headlamp. 7. Close the hood and turn off the lamps.

Condensation can be a natural by-product of this design. When moist air enters the lamp assembly through the vents, there is a possibility that condensation can occur when the temperature is cold. When normal condensation occurs, a thin film of mist can form on the interior of the lens. The thin mist eventually clears and exits through the vents during normal operation. Clearing time may take as long as 48 hours under dry weather conditions. These are examples of acceptable condensation: • Presence of thin mist (no streaks, drip marks or droplets). • Fine mist covers less than 50% of the lens. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)
