How to adjust the aim of the headlights
Why adjust the aim of the headlights
1. You will be able to see better. Lights set too high or too low, or out to the sides, will not give you the optimum illumination of the road ahead. The standard lights are quite reasonable so if you think they are not lighting the road up well they are probably not set right.
2. It's the law. Headlights are required to be set so that they don't dazzle oncoming vehicles. This is checked on the MOT.
3. You have a moral responsibility. Dazzling others is at best annoying, and at worst, dangerous.
You will need:
- Your car with working headlights
- A completely flat and level area and a vertical wall/fence/garage door
- Darkness
- Crosshead screwdriver
- Masking tape
- Tape measure
Method
Before it gets dark, familiarise yourself with the position of the adjuster screws for each headlight.
- Set the Headlight beam level control switch to 0. This control is to the left and below the steering wheel. It is for compensating for heavy loads that push the back of the car down, so to adjust the headlights correctly you need the car unloaded and the control set to 0.
- When it gets dark (it doesn't have to be pitch black, just dark enough to see the headlight beams) move the car right up against a vertical surface (wall/fence/garage door). As close as possible without touching, a few inches.
- Switch on all four headlights. Using masking tape, or something similar, mark the centre of the flat top dip beams, and the centre of the high beams spots with a cross.
- Now back the car away from your vertical surface in a straight line so that the front is 25 feet (7.5 metres) away.
- Adjust the dip beams so they are between 2 and 4 inches below and to the left of the marks you made.
- Adjust the high beams so they are between 0 and 2 inches below the marks and on centre left to right.
- You may find it easier if you only have one beam on at a time. You can either unplug the others or cover them.
And that should be that. Put the plugs back if you took them out, or take the covers off if you did that, drop the bonnet, take the tape off your vertical surface, put your screwdriver away and you're done.
