Why You Need to Adjust the LED Headlight Bulbs

You may be wondering why you need to adjust your new LED headlight bulbs on. Just to give you an idea, you can’t just pop the bulb in and use it. If your LED headlights are not properly aligned, it’s possible for you to accidentally aim the light straight at mirrors of other drivers. When that happens, drivers that are in front of you may lose their vision. This may result in a possible car crash for both of you. Not only will adjusting led headlight bulbs keep you safe from accidents, but they will also make sure no one else on the road gets hurt as well. 

Now that you know why you need to adjust the LED headlight bulbs of your car, the next thing to ask is how to adjust LED headlight bulbs. These points are discussed in the guide found below. 

You can find the steps in the next section.

How to Adjust LED Headlight Bulbs

There are actually two options for headlight bulb alignment that you can choose from. We’ll discuss both options to allow you to have a choice on which method you’re most comfortable with. 

Let’s Start With the First Option

Here are the steps:

1. Clean up the lenses of your car’s headlights.
2. Park your car near a wall with the headlights facing the wall.
3. Make sure that all tires are well inflated as to give the light alignment a good level.
4. Sit in the driver’s seat and turn the low beam headlights on.
5. Use a marker or some tape to indicate the top of the beam.
6. Measure the distance inside the square beam.
7. Mark the bottom of the beam as well.
8. Back your car up a little bit until your vehicle is 25 feet from the wall.
9. Take out the assembly of your headlights.
10. Take the old bulbs out and replace them with new ones (you can refer to your manual to do that).
11. Shine the new lights again and make sure to align their beams to the markers you placed on the wall.
12. Make necessary adjustments if ever the beam doesn’t hit the markings.

The next option is pretty similar to the first one but with the difference that there is more measuring needed, and you don’t need to move your car around too much.
