Headlight reposition

Sorry to ask, but is there a guide anywhere on this forum for a Spider 87 headlight procedure? Tried a search, but nothing. Or I have the workshop manual, but can't find it. Is it in there?

Any thoughts?

Thanks!

in my manual it is in section 40 "Electrical -front combination lights"...well at least the method is where you shine the lights on a wall from 33 ft (10m)

That's cool, I'm not sure that diagram was included in US spec cars, at least not on my '74.

Are dimension D & E the same? If not, do you know what dimension D is supposed to be?

yep.

the WSM says: Interaxis D of the luminous beam should be equal to interaxis E of the headlights

B it gives as 619,56 mm (24.4 inch)....I rounded that to 62 cm!

Obviously the car needs to be on horizontal ground

Note: although this is taken from my USA S4WSM, it does say 'this is according to current italian regulations'.....whether USA is different.....?

I recently had to re-aim the headlights on my car. Since I didn't have any info in my 1971 manual, I looked to the net and found a very similar system at Popular Mechanics:

How to Adjust Your Headlights - Aim Your Headlights

However it turned out not to be immediately practical for me to find a level place with a plain wall 25 - 30 feet away where I could fiddle with the car, a measuring tape, and make marks on some stranger's wall in the dark for half an hour (without getting arrested?).

So, I decided to make a quick effort to get things close: I took my 'daily driver' and moved it to the end of my driveway giving me roughly 15 feet from the headlight lenses to the closed garage door. I marked the car's place in the drive with masking tape: left side, right side, front bumper. I turned on the low beams and then marked the center point where the light from each beam hit the garage door with an '+' made of masking tape. I then made a second mark for the high beams.

I then put my Spider in the same, marked, location in the drive with the front of the headlight lenses as close as I could get them to where the daily driver's had been. I then adjusted the Spider's headlights to hit the same marks on the garage door; when the low beams were right, the high beams hit their marks automatically. The whole process took about 20 minutes.

As far as I can tell anyhow the lights are aimed properly and no math or measurement was involved which is a big deal for me.

I will admit to driving around town scouting out locations with a flat surface and a plain wall on more than one occasion but had the same concerns as you. I finally found a place at a friend's shop that will work ok.

I like your solution, close enough is good enough. Even with E-Code lenses, H4 bulbs and relays I've never had anyone flash me, even with the high beams on. I think the Spider is so much lower to the ground than all the SUVs that they just don't notice.

I usually go to a parking garage. There are a few around me that are pretty deserted on the weekends and dark enough down on the lower level to do it during the day.

on my S4 it is a little more difficult: some german S4's had motorized/adjustable tilt headlights.....mine does.
The horizontal adjustment screw is from the front (as usual) but the verticle adjustment is from behind. The plastic fender inner protector has a small plate you unscrew then you can get to the back of the light. The verticle adjuster is on the headlight motor itself.

Odd idea on a spider, being 2 seater with a small trunk...because you are hardly going to be carrying 3 extra passengers in the back and a few hundredweight of their luggage in the trunk!

I have seen very few spiders with this factory set up, even here in Germany.
