Why is the left headlight lower than the right one?

Don't worry about it being a headlight malfunction - this situation is actually quite normal. According to legal regulations, the low beam of car headlights should be lower on the left side and higher on the right side. If the lights were perfectly aligned horizontally, that would indicate a problem. Here's some relevant information: 1. Headlights: Vehicle lights refer to the lamps on a vehicle, serving as illumination tools for nighttime road driving and signaling devices for various vehicle movement indications. 2. Classification: Vehicle lights are generally divided into headlights, taillights, turn signals, etc. 3. Maintenance: The "soul" of headlights is their bulbs, whose performance affects nighttime illumination effects and directly relates to driving safety. Therefore, using high-quality headlight bulbs is essential to ensure safety.
As a driver with over 20 years of experience who has done plenty of night driving, I initially thought something was wrong with my car when I noticed the left headlight was lower than the right. I rushed to the repair shop to ask about it. The mechanic explained that this wasn't a malfunction but rather an intentional design feature. The left light being slightly lower prevents blinding oncoming drivers with glare, reducing accident risks, while the right light being higher improves visibility of roadside signs and pedestrians for safer driving. This design is actually a standard regulation in many countries. I later tested it myself - if you arbitrarily adjust the lights to be symmetrical, it actually makes turns harder to see at night and could cause disputes. I recommend car owners avoid tampering with the factory settings and keep them as is, since safety is no trivial matter. It's also important to regularly check for aging or loose bulbs to prevent issues during long trips.
