Headlights with "Nippels"
 

Hi guys,

One of our users buyed a 930 Turbo from USA an this car has three "Nippels" at the headlights glas. I cant find a answer why is this?

Thanks for your help in advance

They are called velocity nipples, so I guess it cuts the wind resistance.

The small nipples are used for the correct positioning of a headlight aiming device.

The car must be from California and it is not used to the cold weather in Germany.

now thats funny, my initial thought was along the lines of the post above but I could not craft a clever reply such as his.

when I wash and wax my car, I pay particular attention to those and get a rise every time.

Yes to aim the headlight in the right direction.

I like the other ideas though...haha

Will the real "reason for the nipples" please stand up

Darin, they are for aiming USA DOT spec H5 headlights that came out on the 911 and 930 in 1987 quickly if the special tool is available.

The tool is placed over the headlight and lines up in position on those nipples.
The top of the tool has bubble levels that show when the headlight is adjusted according to USA DOT or department of transportation specs.

Most people adjust their headlights a little higher than the DOT specification from 23 years ago.

Inexpensive round DOT spec sealed beams from many many years ago had those nipples for the same reason.

All DOT spec headlights from years ago put out very little unfocused blurred light compared to euro code headlights.

yeah, I figured that. My comment was strickly for amusment

although they could be for tuning in tokyo

Any idea what that "special tool" looks like? I could see building one and using it as intended to align the headlights.

There are several kits and systems from different tool manufactures but this one seems popular. They should be pretty cheap used as these methods are not used on new headlights.

I go by the eyeball method. Turn the lights on a flat road and adjust as needed to my liking...

Cost? Free...

You can adjust them up against a building too. I have done that many times with excellent results.
