The non-concentrating car headlights may be caused by improper adjustment of the lights or incorrect installation position of the bulbs. Here are some suggestions from SHINESELL AUTOD, but please note that these steps may vary by model, and it’s best to refer to your vehicle’s owner’s manual for exact adjustment steps:
1. Parking position: Park the vehicle on level ground, about 5 meters away from the wall, and ensure that the front and rear positions of the vehicle are even.
2. Prepare tools: Typically, you will need a screwdriver or other appropriate tool to adjust the light.
3. Turn on the headlights: Start the vehicle and turn on the headlights. Make sure all vehicle lights are on.
4. Mark the spot position: Mark the spot position of each headlight on the wall. Small pieces of tape or other removable markers can be used.
5. Adjust the horizontal direction: Find the adjusting screw on the headlight lampshade, and adjust the horizontal screw to make the light spot horizontal and symmetrical on the wall.
6. Adjust the vertical direction: Find the adjustment screw on the headlight shade and adjust the vertical screw so that the light spot is vertical on the wall.
7. Check the position: Check again whether the position of the light is accurate and ensure that the lights on both sides are adjusted properly.
8. Test drive: Carry out a short test drive to check the effect of the lights. Make sure the light spot is bright enough and does not dazzle other drivers when driving at night.
Please note that these steps provide general guidance and actual adjustment steps may vary by model. If you feel unsure or unfamiliar with car maintenance, ask a professional car mechanic for help. Also, make sure you follow local traffic regulations when adjusting your headlights to ensure the lights do not cause distress to other road users.
