Default 2004 XJ8: How2Adjust Low Beam Headlamp

Hi guys... I've noticed my low beam headlamps aim very low ahead of the car. This forces me to use the HIGH beams on rural roads, which pains others coming towards me. When I dim the lights, I can only see the road well for about 50 feet ahead of me... not good!

Is there a simple adjustment screw/etc.? And where is it (if so).

I recall from my youth one would park in front of a wall (garage door) back about 15 feet and adjust the beam focus to a recommended settings (X & Y).

Please respond if you've adjusted yours.

Cheers,

Kyd

Kyd,

You've posted this in Off Topic section. I think you'd get a better response in X350 section. Do you want me to move it?

First, do you have HIDs?
1. They might be stuck in the "Day-Light" mode.
2. Check on your NAV screen, settings for the lights, see if Day-Light mode is on or off.
3. If on, the motor for the low beam adjust might be out.
4. If the motor is OK---
5. The adjustment screws for the low and high beams are on top of the light assy. One will adjust "up-down", the other -"left-right".

I did my adjustments last month, noticed my low beam was too high.

Thanks Reyes. Can you tell me how to get at the screws?

Cheers

The screws are under the plastic panel accessed though the 2 openings above both Headlights. The screws are plastic!

Yes, that would be nice... I'm quite inexperienced on this site... and always stumble when it come to posting a NEW question... I wish our 'dashboard' had a 'new thread' or 'new post' button...

Chees,

We don't have the HID's... when wife gets home I'll check your ideas out... Thanks...

BTW, is there any info on where is the optimal spot for adjusting the low beams? As I originally stated, I remember we used to park a certain distance from a well and measure up on the wall the optimal target...

Chees,
Kyd

Kyd,

The JTIS procedure for headlamp adjustment is:

Prepare the vehicle for headlamp adjustment:
1. Place the vehicle on a level surface.
2. Before adjusting the headlamps, check them for faulty lenses, reflectors and blackened bulbs, and install new components as necessary.
3. Check the tire pressures and correct as necessary. The vehicle must be at normal unladen weight.
4. Normalize the suspension.
5. Adjust the headlamp using the adjustment bolts.

That's it. Absolutely no detail on measurements for the low beam setting!

I remember the same procedure as you on parking a set distance from a wall and measuring low beam height up the wall. Here's a link to an article on this:

Don't be daunted with the detailed instructions on the website, with a little practice, both headlights can be adjusted within 5 minutes.

I see only two adjusting screws in the picture so I assume you adjust both hi and lo beam at the same time, ie when you raise the lo beam you also raise the hi beam. Am I understanding this right ? Second question if there is a leveling motor on HID lights what exactly is it leveling? If you can raise the beam mechanically then are you 'levelling' them relative to the load in the car?

"psg" you are correct, the red arrow points to the "UP-DOWN" adjustment screw.

When you adjust the headlight, you are adjusting the primary "Beam Angle" to keep from blinding on-coming drivers. The "HID" leveler operates from input received from a sensor to keep the "Beam Angle" at the same height.
