How do you know for sure that your headlights are aimed properly? If they illuminate only the street right in front of your car, they’re probably too low and if other drivers are flashing their high beams at you, they’re probably too high. Here’s how to find out for yourself. On a level ground, park your car with the headlights facing a wall or garage door about 25 feet away. The highest point where the light shines on the door should be about the same or maybe a little bit lower than the height of the headlights themselves measured from the ground and it is perfectly normal for the driver’s side headlight to be a little bit lower so it doesn’t blind oncoming traffic for owners of older Honda’s Acuras in some luxury models. Check for a bubble level over each headlight. That can help set the vertical height, but if you do that, make sure the car is on a level surface to begin with. Always check the height with the car loaded the way you will be driving it. Most of the time that’s because the load in the trunk can change the height. If your headlights are aiming to lower high, your mechanics should be able to realign them relatively quickly using adjustment screws under the hood.
