We can find 2 major concerns caused by improperly adjusted lighting of your Citroen C5. First of all, they could cause dazzling of other motorists or not properly light the road because of an excessively low light intensity. In each case, a bad adjustment could be a danger.

However, this problem can very quickly happen, for example when you have chosen to change your headlights. You can inadvertently adjust the light adjustment. Especially for installing LED bulbs or changing a damaged bulb. It is therefore useful to learn how to correctly adjust the lighting of your Citroen C5.
In this way, given that the lighting on your car allows you to see and also that you are seen by other motorists, improper adjustment of the lights of your Citroen C5 may be penalized by a 3rd category fine that may be worth up to 68 euros. If you want more information about the fines related to traffic lights and signals, you can refer to the following website because it will explain everything that is important to know on traffic light compliance rules
Note that the price for adjusting headlights may vary between 29 and 34 euros.
So in order to avoid all this we will explain in a very simple way how to adjust your headlights yourself.
Important thing to know : this tutorial is not intended for the adjustment of xenon bulbs quite simply because they have the specificity of providing a very high electrical voltage and that is why any manipulation must be carried out through mechanics.
For the adjustment of standard bulbs such as filament or halogen bulbs we will firstly allow you identify headlights that require adjustment.
Then in a second step we will allow you to to know if the headlights are correctly adjusted on your Citroen C5 in order to validate the technical control and drive safely.
Finally we will guide you in the manipulation to simply adjust the lighting of your lights on your Citroen C5.

1- Identify the headlights on my Citroen C5 which must be adjusted

Your Citroen C5 is equipped with several front and rear headlights, but only some of them must be centered to ensure their correct operation. In fact, the purpose of the low beams and the main beams is to see the road in the dark, so a good adjustment is essential.
Conversely, a brake light or a flashing light will not require alignment when they are put in place quite simply because their objectives are to signal a manipulation by the driver.
So in this tutorial we will only focus on the low beam and high beam headlights on your Citroen C5. If you notice that a lighthouse is opaque, do not hesitate to consult our article: Opaque headlights on Citroen C5, what to do?

2-How do I know if the headlights of my Citroen C5 are properly adjusted?

Now we will allow you to properly assess the height of the beam of your headlights.
This will give you the opportunity, for example, to know if your Citroen C5 validates the conditions of the technical control or not.
Therefore the objective of this step is to draw the marks on a wall. You will need to make 2 horizontal marks to check the height of the light beam

  • left height
  • height right

Following this step, you will therefore have drawn a horizontal line on the wall which will give you the possibility of determining if the light beam of the headlights of your Citroen C5 is at the right level.
To do this, it is essential to install the vehicle in the correct position in order to achieve a good adjustment.

1- Position your Citroen C5 to check the setting

  • The first thing to do for this is to park your Citroen C5 on a flat terrain (avoid parking on slopes, not smooth, etc.), point the front of the car towards a white or light-colored wall.
  • If you can 10 meters from the wall or because of a lack of space you have the possibility of making the estimate at a distance of five meters but it will be less exact
  • Try to do the manipulation at the end of the day when the natural light is lower

2- Prepare your Citroen C5 before adjustment

  • Tires must be inflated
  • Your vehicle should not be loaded so as not to distort the centering
  • Finally make sure in the cockpit of your Citroen C5 that the headlights position is at 0

3- Material necessary to calculate the lighting on my Citroen C5

    Equip yourself with the following equipment for handling
  • One meter to observe the height of the headlights for your Citroen C5
  • A rule and or a level
  • A pencil or colored tape
  • A screwdriver
  • 4-Calculate the height of the lighting on my Citroen C5

    Measure the distance that there is between the bulb of the low beam or the high beam with the ground on each side of your Citroen C5 and transfer it to the wall. Draw a marker or you have the possibility of positioning a scotch tape.
    If the light beam exceeds the mark it means that your lighting will blind other motorists.
    If on the contrary they are too low then you have a limited brightness.

    Adjust the height of the low beam and high beam on my Citroen C5

    Therefore once the mark hung on the wall open the hood of your Citroen C5 in order to adjust the headlights.
    Locate the screw near the optic and adjust by screwing from right to left to adjust the height.
    The objective is for the light beams of your Citroen C5 to be just below the mark to sufficiently illuminate the road without dazzling.
    Once properly adjusted you can close the hood and do a test overnight.
