The Predators are the best fiber optic lights on the market. They also fade out when the car is shut off like the dome lights. A really slick set. I am going to put them in my BMW shortly.

A pot is simply a variable resistor. Connecting one in series with the headlight would basically adjust the speed at which the headlight buckets move assuming it could handle the current. If you literally took a $1.75 pot (you are seriously overpaying for your pots) and connected it up, the first time you hit the lights you would have a bit of smoke and a dead pot. A rheostat (a higher wattage wire-wound pot) would work but again you would just be adjusting the speed at which the lights raise and lower.
I'm not exactly sure how the aftermarket pivot kits adjust the position of the lights since the headlight motors are simple motors and not servos with basically no feedback on their position past "UP" and "DOWN". My guess would be a simple timer that simply cuts the motor after a certain amount of time, thus stopping the lights in roughly the same position every time...

I think your pretty close if not 100% correct. Im no wiring expert, and before i got the pivot controller, i hadnt a clue as to how to even make something like that... and too many people think they know how to make it...but dont. idk, i didnt spend too much on it, and its just one more thing inside my car that people ask about...
should have said 'op-amp'.. should have realized you'd get **** about it.
also it's voltage threshold 0-5V , not timer induced control other wise simply changing the lenght of a pivot arm would induce the same effect.. and it dosen't the motor will continue to load up till it burns out trying to reach it's limit point, internally.

Back in 1995 when I did the sleepy eye mod on my FC at the time. I used a 2 reed switches and magnets to control them. I did this so they only rise to the same height every time. Because their is no feedback control in the headlight so if you don’t tell both of them where to stop they raise up at different speeds and stop in different locations

I got mine for 30 bucks, prolly spent 3 hours (it was at night..thats why it took a long time) getting it hooked up. In retrospect i wish i had done it the cheper way. works almost the same, just a little less control on where the lights stop comming up. And requires a tear down on the dash (and those of you with s5's know that those little plastic tabs break WAY too easy) .
I would like to do the dual headlight mod, with the halos, but id go the HID route, and get a pair of BMW halos, and custom fit those. The fiber optic ring looks 100x better IMO. Not to mention the HID rout with the BMW projectors get rid of a lot of scattered light that you get with the cheap fake halo bulbs, and the cheap HID kits a lot of people sell/buy...

I've been wanting to do this, but how do you keep the headlights level? When I tried it I couldn't get both headlight the same height as they would move at different speeds.
Also, your car looks strikingly familiar to mine...(Click for larger pic)

flip your lights to the up position. they will not move cuz circut is broken
then tap the switch on then off. it will raise them a few. (i could have bought a button but didnt see one)
now i can have headlights on and lights half way up. unlike just pulling the fuse and not having lights.
to raise lights all the way. flip switch to on. they will raise all the way.
