Headlight Aiming - Quick Method

This is a pretty quick and easy way to aim your headlights without getting too technical.

If the headlights were a long way out of alignment before starting this procedure, you may need to do it twice. If you need to, it should be fairly obvious after taking it for a drive.

2 Headlamps (eg 2 x H4 Lamps) 4 Headlamps (eg 4 x H1 or H3)

Step 1.
The car should be set up for "average" conditions:
- half a tank of fuel
- correct tyre pressures
- someone in the drivers seat

You'll need:
- some insulation tape
- a blanket
- whatever tools are required to adjust the headlamps (usually a phillips head screwdriver)

You'll need:
- some insulation tape
- a blanket (two if both high and low operate at the same time when high beam is selected)
- whatever tools are required to adjust the headlamps (usually a phillips head screwdriver)

Step 2.
Find a level area that has something like a brick wall that remains level for at least 6 metres at right angle to the wall. A reasonable garage should do the trick.

Step 3.
- Drive towards the wall and stop as close as possible to the wall. When you do this, ensure the car is as close to 90 degrees from the wall as possible and that the wheels are straight. Take your time to get this right as any discrepency will affect the accuracy of the aiming significantly.
- turn on high beam
- using the insulation tape, mark the wall with a cross with the insulation tape in the EXACT centre of where the beams strike the wall

- turn on high beam.
- using the insulation tape, mark the wall with a cross with the insulation tape in the EXACT centre of where the beams strike the wall. If low beam remains on when high is selected, you may need to cover the low beam lamps for accuracy purposes.
Step 4.
- Move the car back in an exact straight line a distance of 2.5 metres
- cover one headlight with the blanket and turn on the high beam again
- adjust the headlight so the centre of the beam is exactly on the cross on the wall
- put the blanket over the other headlight and adust as necessary.
Step 4.
- Move the car back in an exact straight line a distance of 2.5 metres
- Cover one headlight with the blanket and turn on the high beam again (cover low beam with another blanket if low beam is on as well)
- adjust the headlight so the centre of the beam is exactly on the cross on the wall
- put the blanket over the other headlight (and low beam if applicable) and adust as necessary.

Thats it for the high beam.
That should be all you need to do as the adjustment should have aligned the low beam as well. Take it for a drive and see how it looks. If it seems out, just repeat the process again. Step 5.
- measure the distance between the high and low beam lamps on the vehicle
- using the insulation tape, put another cross on the wall 1) the same distance horizontally as the distance measured above, and 2) 25mm below the high beam aiming point
- cover one headlight with the blanket and turn on low beam
- adjust the headlight so the centre of the beam is exactly on the seconadry crosses on the wall
- put the blanket over the other headlight and adust as necessary.
  That should be all you need to do, so take it for a drive and see how it looks. If it seems out, just repeat the process again.
