Adjusting Headlights

Post by Patrik » Sun Jun 13, 2021 6:59 am

I’ve found the lights on my bog standard E85 2.0i pointing down a bit too much, even when I set it on the dashboard to the lowest setting, ie. with the lights pointing highest I can’t really see very far while the puddles and potholes close by are illuminated perfectly well. Now I’d like to at least check whether they are set up properly, would anyone know if I drive up to a wall, how far should the nose of the car be and how high the line on the wall for the headlights?

Adjusting Headlights

For a rough guide - I did my 2 Excite replacements on a 2.5 E85 Halogen set up and it passed the mot fine.
Mark the center of each light with a marker.
Measure the height of the dot from the ground = A
Measure the distance between the two dots = B
Put two vertical tapes on a wall distance B apart
Put two horizontal tapes at height A intersecting the verticals.
Put a horizontal tape 2in down on the left and 4" down on the right ( For RH Drive)
Park car 3' from tapes and adjust lights one at a time to be centered on the tape intersection of A/B

Reverse about 25/30 ft directly back and bounce the suspension a couple of times.
One light at a time

Adjust heiight of low beam cut off so it hits the RH 4" and LH 2" lines below horizontal center and is centered on the vertical line.

Mains should be set with center of beam on the A/B intersection ie Straight Ahead, parallel to the road.

When the car is loaded the drivers adjuster will need to adjust the lights down to compensate so start with it at the highest setting

That should het you a pass at MOT
