Headlights that are not adjusted properly can pose many problems for both the driver and oncoming traffic. If headlights are pointing too high, even the low beams can be too bright for oncoming traffic. If the headlights are pointed in the wrong direction it can be difficult for you to see the road in the dark. Mechanic shops charge a fee to check and adjust headlights. Learn to adjust headlights on a Honda Civic DX and fix the problem yourself.
Park on a flat surface. Empty everything out of the car except what is normally kept inside the car. Have a person close to your weight sit in the driver's seat to get the car as close as possible to normal driving conditions. Also check to make sure the tire pressure is at the correct pressure before leveling the headlights.
Open the hood and locate the horizontal adjustment indicator behind the headlights. This indicator is located on the back of the headlight housing on the side closest to the outside of the car. It looks like a series of bolts and nuts, but has small gears on it that are the same color as the plastic on the back of the headlight. The indicator should be aligned with the "0." If the indicator is not aligned at the "0" mark, use a Philips head screwdriver to turn the screw on the adjustment gear until the "0" mark is aligned.
Locate the vertical adjustment indicator. This indicator is located near the top of the back of the headlight. It is a bright green colored tube of liquid, similar to a carpenter level. The bubble in the level should be in the center, between the two longest marks on the tube. If the bubble is not located in the center, use a Philips head screwdriver to turn the screw in the gear, which is located on top of the headlight.
Repeat the steps for the remaining headlight, making them both identical.
