Is it normal for low beams to be uneven in height?

[DeKingston]

It is normal for low beams to be uneven in height. Generally, the left low beam is set lower to ensure safety during oncoming traffic, while the right low beam is set higher to illuminate the road further ahead. Below is an introduction about low beams: 1. Lighting safety: Low beams are crucial for driving safety at night or in low-light conditions. 2. Headlight adjuster: The headlight adjuster refers to a device that corrects the direction of the headlights when they deviate from the standard due to factors such as vehicle load, prolonged vibration, or uneven road conditions. Its function is to restore the headlight's illumination direction to the standard position, thereby improving lighting effectiveness. 3. Right-hand traffic principle: Steering wheels are designed accordingly. Vehicles drive on the right side, so oncoming traffic typically approaches from the left. For safety reasons, automotive design ensures the left beam is lower to avoid impairing the visibility of oncoming drivers.

A few days ago, I noticed one of my car's low beams was higher than the other while driving—definitely not normal. It happened on a rural road at night with poor visibility. The uneven lighting messed up my field of vision, and I almost scraped against a roadside obstacle. The root cause could be a misaligned bulb, a stuck adjuster, or a loose bracket causing tilt. My advice: Park on level ground, turn on the lights, and check the beam height difference against a wall. If the gap is significant, don't cut corners—head straight to a repair shop for adjustment. Key consideration: Headlights should be symmetrically aligned to ensure clear nighttime illumination without blinding oncoming traffic. Have them checked during regular maintenance to nip issues in the bud. Safety first—delaying this risks accidents and higher repair costs.

As someone who frequently takes family members on long trips, I must say that uneven low beams should never happen. That day, while driving back with my kids, the left beam was lower and the right one higher, with scattered light that failed to illuminate the potholes ahead, nearly causing an accident. The likely causes are bulb misalignment due to bumps, loose adjustment mechanisms, or wiring contact issues. The solution is simple: after parking, manually check the beam balance—if it's off by a lot, get it fixed immediately. Night driving is high-risk, and uneven lighting increases blind spots, potentially leading to rear-end collisions or scrapes. It's advisable to regularly check headlight alignment—developing this good habit can ensure you arrive home safely.

From a driving perspective, asymmetric low beams are unacceptable. The difference in beam height typically stems from common issues such as improperly installed bulbs or faulty adjusters. Immediate action is required: park and adjust the lights against a wall to ensure even illumination for clear road visibility. Otherwise, increased blind spots at night can easily lead to accidents.
