Xenon headlamp alignment

[Nicky]

I know my right headlight is out of alignment now after replacement. Any hints on aligning Xenon headlights please.

[Graeme]

Same 2 adjusters as the halogens.

This D4 came with Xenons, no idea as what you mean with "Same 2 adjusters as the halogens" What adjusters where and how please?

This is a MY10 headlight but your's will be similar. A long Phillips head screwdriver is required.

Thanks, not sure what you mean, where and what with the long Phillips screwdriver. I think it was in the fitting into the car of the headlamp not the adjustment.

The screwdriver is to turn the two adjustment screws - the PDF shows where the vertical and horizontal adjusters are.

If not fitted correctly, you would see it pretty quickly - are the new light units from a LHD car maybe? How are they out of alignment?

I think it was in the fitting of the headlamp into the car of the headlamp not the adjustment. i.e. the headlamp does not have to be totally out
of it's location.

There is no adjustment of the fitting into the car itself - they just go into their spots and you push the levers down to lock in - adjust the lamps as described above.

If you cannot get a screwdriver in with the housing in the car - note what adjustment is needed, pull out the fitting and adjust the screws, reinsert the light housing and check alignment - repeat if needed. Taking the light housing in and out of the car is a 2 second job once the grill is removed.

Thanks, now the direction (clockwise/anti-clockwise) of the adjusting screws please. Experimenting taking the lights in and out seems a silly LR after-thought.

D4 headlights don't need to be removed to be adjusted. If you shine the lights onto a wall after dark you will very quickly see in which direction to turn the adjusters to match the new headlight's beam with the other. I find that adjusting whilst on low beam is best because the cut-off is very distinct. Don't forget to also adjust left/right if needed.

Thanks, is there room to put your hand in?

[Graeme]

The adjusting screws are external and accessed straight down from the top - no need to put any hands down if the screw-driver is long enough. The adjusters are white/cream.

Watch this, not a D4 but the same principle.

Sorry, hex not Philips although I didn't use a hex driver.

It’s dual. It’s a hex and inside at the bottom of the adjuster is a Phillips mould. For this reason your philips needs to be narrowish

Thanks, but not sure what you mean, please explain

Probably why I recalled using a Phillips!

Thanks, the D4 light adjust looks like the LR sport video that you posted.
