Misaligned beams either blind oncoming traffic or limit your view. Here’s how to correctly align them up-down and left-right, step by step 👇 ⚙️ 1️⃣ Preparation Park 3 meters from a flat wall; Keep tires properly inflated; Empty trunk; Switch adjustment wheel (0–3) to position 0; Turn on low beam. 🔧 2️⃣ Vertical (Up–Down) Adjustment Locate the vertical screw on top or behind the headlight: 🔄 Turn clockwise → beam goes down; 🔄 Turn counterclockwise → beam goes up. The light cutoff should sit slightly below the headlight center line on the wall. 🔩 3️⃣ Horizontal (Left–Right) Adjustment The side screw shifts the beam horizontally: 🔄 Clockwise → beam moves right; 🔄 Counterclockwise → beam moves left. 👉 Left beam should point slightly right of center (to avoid glare).👉 Right beam should illuminate the roadside. 🧱 4️⃣ Wall test method Mark both headlight centers and an upper horizontal line.Adjust until the beams align symmetrically and stay below the marked height. European headlights always project a slightly raised right side pattern – that’s normal. 🧰 5️⃣ Professional alignment For LED/Xenon/MATRIX systems, have them adjusted at a garage with a beam tester (regloscope) or at an inspection station (MOT/ITP). 🪶 Conclusion Headlight adjustment up down left right ensures perfect illumination without dazzling others – simple, quick, and worth doing regularly. 🔗 External source: Hella.com – Headlight technology and adjustment standards.Diagnoza BAM – Internal automotive tutorials. ✍️ Author: Bejenaru Alexandru Ionut – alexandrualex228@gmail.com
