Having properly adjusted headlights is essential for safe night driving. Misaligned headlights blind oncoming traffic and fail to properly light the road ahead. The Honda Civic headlight aim is adjustable using screws located on the headlight assembly. With some simple tools and a flat workspace, you can optimize your Civic headlights in less than an hour. This guide will cover the steps for adjusting both low and high beam alignments. Read on to learn how to adjust your Honda Civic headlights for maximum road visibility and safety.
Locating The Headlight Adjusting Screws
The first step in adjusting your Civic’s headlights is accessing the adjustment screws. These screws can shift the direction of the headlight beam up, down, left, and right. Here’s how to find them:
Low Beam Adjusters
The low beam adjusting screws are found on the rear side of the headlight housing. There will be one on the left and one on the right. They have a small plastic cover that can be pried off with a small flat head screwdriver.
High Beam Adjusters
The high beam adjusters are located on the top of the headlight assembly under a rubber weather cover. Pull back this cover to access the adjusting screw.
Check that the adjusters can turn freely before attempting any adjustment. If they are seized, apply penetrating oil and allow it to work before trying again.
Centering The Headlights
Before any adjustment, the headlight bulbs must be centered in their housings. Here is the process:
- Turn the headlights on and observe the beam pattern on a wall or garage door.
- If the pattern is drastically off-center, you’ll need to re-center the bulbs first.
- Turn off the lights and remove the headlight housing from the vehicle.
- Look for the centering screws on the housing and adjust them until the bulb looks evenly positioned when turned on again.
- Reinstall the adjusted headlight housing once centered.
Adjusting Low Beams
The low beams provide visibility directly in front of the vehicle, without blinding oncoming drivers. Here is how to properly adjust Honda Civic low beams:
Preparation
- Park your Civic on flat ground 25 feet from a garage door or wall.
- Measure and mark the centerline of the headlights on the wall with tape. Do this for both low and high beam bulbs.
- Adjust Honda Civic Headlights so low beams are on. Do not use high beams for this adjustment.
Adjustment Steps
- Locate the low beam adjuster screws and loosen them.
- Turn the adjusters until the brightest part of the beam is 2 inches below and to the right of the taped centerline.
- Tighten down the adjuster screws once alignment is achieved.
- Repeat adjustment on both headlights for proper left and right alignment.
Adjusting High Beams
The high beams throw light farther down the road to maximize visibility. But they need to be aimed parallel with the low beams. Follow these steps:
Preparation
- Follow the same preparation steps listed for low beams.
- Switch on the high beam headlights, leaving the low beams off.
Adjustment
- Loosen the high beam adjuster screws.
- Rotate adjusters until beams are in line with the taped centerline. They should be parallel with the low beam cutoff.
- Tighten down the adjuster screws once proper alignment is reached.
- Repeat for both headlights to complete adjustment.
Troubleshooting Poor Headlight Aiming
Sometimes adjusting the aim alone doesn’t resolve beam alignment issues. Here are some other problems that could be affecting your headlight aim:
- Bulb seated incorrectly in housing
- Moisture or fog inside housing
- Damaged or cracked housing
- Wrong bulb type
Carefully inspect your housings and electrical connections if adjustment doesn’t improve aim. Moisture or physical damage will require headlight service to restore proper performance.
Adjusting Headlight Brightness
The brightness of your Honda Civic’s headlights can also be tweaked for maximum visibility. Here’s how:
- Locate the headlight leveling knob next to the headlight switch.
- With headlights on, rotate the knob up to raise the beam angle and down to lower it.
- Adjust until beams shine approximately 90 feet ahead of the vehicle.
- Test changes at night to verify adequate visibility without blinding other drivers.
When To Re-Adjust Headlights?
Your Civic’s headlights will need periodic realignment as components age and settle over time. Follow these guidelines on when to re-adjust:
- Every 6 months or 6,000 miles
- After hitting a large pothole or curb
- After front-end collision repair
- When bulbs are replaced
- If beam pattern changes over time
Routine Adjust Honda Civic Headlights ensures you get the safest and best headlight performance. Don’t wait until they are drastically misaligned, as that can create hazardous driving conditions.
Professional Adjustment Alternatives
Adjusting headlights yourself requires some mechanical skill and patience. If you are unable to adjust the lights on your own, seek help from a professional auto mechanic. Many shops have special headlight aiming machines that can accurately align beams to the factory specs. This small added cost is worthwhile for safety and peace of mind.
