Default Headlight Question

Hi all. I want to aim both my headlight low beams and my fog lights. i know I need a t15 hex screw. For the FOG LIGHTS- which way do i have to turn them to raiser/lower? Looking at the light face on do i turn left to lower and right to raise?
For the HEADLIGHTS... Which moves them up and down? There is a post here that instructs how to but for euro headlights. It is confusing. Are there three points where the lights can be aimed? Thanks for your time

P.S- My headlights are aimed wayyy too low and my passenger fog light is aimed wayyyy to low. Thanks

i believe clockwise is up and counter is down.

the long golden rod will move the headlights up and down.

The instructions for the Euros is the same principle it's just a different bulb. Hopefully this will help:

Aiming your Head Lights

Preparation:

Prepare the aiming area. You can use the garage wall providing its at least 25’ from the car and the ground is level.

Mark some calibration lines using chalk or masking tape:
Find the center of the headlight and measure the distance to the ground. Mark a horizontal line on the surface (garage door or wall) using masking tape at the same distance from the ground.
Stick a piece of tape in the center of the windscreen and another on the rear glass to use as reference marks.
Line these up from behind the car and use them to mark the centerline of the car on the .
Measure the distance between the center of both headlight lenses and use this to measure from the center point you just marked on the surface.
Make sure the tire pressures are correct and the tank is full or the calibration may be out. Park the vehicle square with the aiming surface. Close the doors and rock the car to stabilise the suspension.

Adjustment

Horizontal and vertical aiming is done by moving the adjusting screws which moves the headlamp capsule in relation to the headlamp frame. The horizontal adjustment screw is located on the inboard side of each of the headlight assemblies and covered by a plug. The vertical adjustment screw is located on the inboard side of each of the headlight assemblies below the lower edge of the headlamp bezel. Its a long golden rod. I think it’s a #15 torx.

Raise the hood.
Raise the headlamps.
Remove the headlamp adjustment screw plug from the headlamp bezel. Reach under the headlamp bezel and push out the plug from behind.
Turn ON the low beam lamps. Block the light from the passenger lamp to allow you to adjust the drivers lamp. Don’t cover the headlight or it may get too hot.
Inspect the horizontal aim. Make the adjustments with reference to the lines and numbers on the aiming chart below
Adjust the aim using the horizontal adjusting screw, to align the break point (3) of the high intensity zone to the headlamp vertical centerline (1), within the range of 38 mm (1.5 in) to the left (5) of the lamp vertical centerline (1), to 38 mm (1.5 in) to the right (4) of the lamp vertical centerline (1) on the aiming screen.



Inspect the vertical aim.

Adjust the aim using the vertical adjusting screw, to align the upper edge of the beam horizontal cut off line 114 mm (4.5 in) below (7) the headlamp horizontal centerline (2), within the range of 76 mm (3 in) below (8) the lamp horizontal centerline (2), to 191 mm (7.5 in) below (6) the lamp horizontal centerline (2) on the aiming screen.

Install the headlamp adjustment screw plug. Push to secure.
Turn OFF the headlamps.
Lower the hood.

Your light pattern should look roughly like this when you’re done.

Fog Lamp Aiming

There is no horizontal aiming for the C5 foglamps

Preparation:

Prepare the aiming area. You can use the garage wall providing its at least 25’ from the car and the ground is level. Make sure the tire pressures are correct and the tank is full or the calibration may be out. Park the vehicle square with the aiming surface. Close the doors and rock the car to stabilise the suspension.

Mark some calibration lines using chalk or masking tape:
Find the center of the headlight and measure the distance to the ground. Mark a horizontal line on the surface (garage door or wall) using masking tape at the same distance from the ground.
Stick a piece of tape in the center of the windscreen and another on the rear glass to use as reference marks.
Line these up from behind the car and use them to mark the centerline of the car on the wall.
Measure the distance between the center of both headlight lenses and use this to measure from the center point you just marked on the surface.

Adjustment

Raise the hood.
Raise the headlamps.
Turn ON the low beam lamps. Block the light from both headlamps to allow you to adjust the fog lights. Don’t cover the headlights or they may get too hot.
Turn on the fog lamps

Insert a torx driver through the front fascia deflector access hole to reach the fog lamp vertical adjustment screw
Adjust the fog lamp up or down until the top edge of the high intensity zone is 4” below the horizontal centre line.



Turn off all the lights

Maybe this picture will help for those of us to lazy to read:



As for the headlights:



I used this picture to describe something to someone else but you get the gist of it. Whatever you do, don't turn any of the headlight adjusting screws without lubing them first!!! There is no fix after you break the adjusting screw. You have to buy another headlight at a whopping $700 give or take!

Here are the revised DeeGee/Junkman How Tos

Measure the distance between the center of both headlight lenses and use this to measure from the center point you just marked on the surface.
Make sure the tire pressures are correct and the tank is full or the calibration may be out. Park the vehicle square with the aiming surface. Close the doors and rock the car to stabilise the suspension.

I'm preparing myself mentally to try to adjust my headlamps without breaking the 'Golden Rod'. I'm reading all the suggestions and they make great sense. One thing I'm seeing right off that would help loosen up the stubborn gearing, without using the Golden Rod to do it, would be to put a wrench to work on the end of the threaded shaft running the the gearing that the Golden Rod controls. Sure, you might mess up some threads on the very end of the shaft but that area doesn't come into play anyhow, does it? And using a wrench with copious amounts of WD40 should loosen it up rather easily anyway it seems.

Any thoughts on using this process?

One other thing - the long Golden Rod apparently controls the vertical adjustment. I understand there is a shorter screw controlling the horizontal. Does that shorter screw have the same problems the longer Golden Rod does?

Note: I STRONGLY reccomend squirting WD-40 (or similar) on the gear mechanism for the adjusters or they WILL break. This may require taking the headlight out to get at it.... but the extra 5 minutes is worth having a functional headlight adjuster.
