Masking Tape and Scissors:

If you have to make any marks on your wall or in your garage you can use masking tape as it will be easy to remove it later when finished.

Step by Step Procedure of how to aim Projector Headlights:

  • The first step is to clean both of the projector headlight lenses.
  • Park the car in a flat parking space and it should overlook the vertical screen. This can be anything like your garage door or a flat wall, etc. You should need more than 5 feet of clearance among your front bumper of the car and anywall. You need more than 5 feet clearance because you will have to take a reverse of 20 feet away to do the real adjustment.
  • Then you have to make sure that the surface should be a leveled If there is anything in the car you have to remove it and keep it out to make sure that your car is flat. If the car is inclined due to a heavy load in it, there would not be any proper accuracy.
  • Then you have to ensure that your suspension system is settled. For more accurate adjustments, inflate all tires to a selected psi capacity and also make sure that the gas tank of your vehicle is at least half full.
  • Start the position of the projector headlights by adjusting the screws of the exact headlights. Most manufacturers have put both the vertical and horizontal screws. There will be two screws. One is for the vertical and the other one is for the horizontal adjustments. The first screw will be at the top and the next screw will be within the housing which is on the inside.
  • By making use of a masking or a painter’s tape, you have to mark both the horizontal and vertical center lines for the two headlights. You can either draw one long, nonstop line or small sections where the bright areas of the headlight beams fall. The marks will help you to identify where the beams should be centered.
  • If one headlight is burned and if you are using two separate horizontal tape lines, draw the line at the same height from the ground. Then you can measure the distance between the headlight centers and use that measurement to plan the vertical tape lines on the wall.
  • Then you have to back up your car for at least 20 feet and the car headlight cut off should be straight between the two marks in which you have made.
  • Here if the cut off is not among the marking which you have made then it means that the projector headlights need an arrangement. To make an adjustment, turn the top adjusting the crew which helps to raise or to lowers the beam of the headlight. If you turn in a clockwise direction it raises the headlight and if you turn in the anti-clockwise direction it will lower the beam. Make the adjustments until you get the headlight beams to be at a level and by doing this you can aim the projector headlights at home by yourself.
