If you examine this sequence frame by frame, you'll see these stripes appear & disappear exactly every other frame. That makes me think it is not in the digital transfer or any subsequent processing, but in the original footage.I cannot think of any transfer process that would divide these frames so precisely.
I have looked at the current BluRay release of this as well as the gif & excerpt posted by the OP & it matches exactly. The BluRay is at 23.98 fps, which is a bit of a kludge to map to the old US/Japanese NTSC video system Don't ask;) , but is close enough to the original 24fps that inter-frame aberration should happen infrequently.
I don't think it could be any kind of physical 'shake' of the vehicle or lights - because the chances of that syncing perfectly to frame rate would be astronomically small.
The only conclusion I can draw at the moment is that there may have been something in the shutter/gate mechanism that presented itself slightly differently on alternate frames. I'm not really sure how this may happen. I've discovered that the camera used, a Mitchell BNCR, may have had an optical splitter fitted, which would present light to the film & to an eyepiece for the cameraman.
There may have been a moving pentaprism design somewhat akin to a [D]SLR ([digital]single lens reflex) camera - alternating between sending light to the film & to the camera op. To my admittedly limited knowledge, there was a 'movie' version of this which rotated to send the light in alternating directions - to film, then to the camera op, 24 times a second.
It may have used a beam splitter, the science of which hurts my brain;) The simplest version of this seems to be the pellicle mirror. These were first introduced as early as 1938, but even to this day they are not popular in 'stills' cameras. The pentaprism remained the most common structure until quite recently when mirrorless cameras started to come to the fore. These use a digital screen as a viewfinder, eliminating the need for a separate optical path.
The streaking is an aspect of the lens flare you can see through most of the shot - light being reflected inside the lens and camera body itself. It's at its 'worst' when the headlights are pointing more directly at the lens.
(Edited) I originally noted that the flickering in the GIF was not every other frame, and only later was advised that the GIF is not a frame-by-frame transfer but is rather running at 20fps. Looking at the video clip, I see that it is indeed showing streaks every other frame.
There is nothing I am aware of in the Mitchell or any other 35mm movie camera that operates on every other frame: the entire mechanism is built around one cycle per frame. Likewise, there is nothing I am aware of in the film printing process that alternates frames. However, this is not the case with the conversion of film to video.
There are several different ways to transfer film to video, and some of them use dual cameras or rotating mirrors or prisms in a way where adjacent frames go through different optical components. My best guess is that this was transferred using a rotating mirror telecine and that one side of the mirror was dirty.
Side note on telecine: a big engineering problem the first telecine machines had to solve was converting 24fps film to 60 fields (30 interlaced frames) per second NTSC television, which made them complex. However, because there was also a need to convert to 50 field (25 interlaced frames) per second PAL television, machines were improved to be variable rate, and then eventually cameras were changed to capture higher resolution progressive scan images. My best guess is that one of these kinds of machines, rather than a more expensive frame-by-frame laser scanner like the kind used now to create digital intermediates for visual effects, was used to transfer this film to video.
One other observation: There is very little motion blur in the image. Looking at frames 110-112 of the GIF (and corresponding frames in the video), you see huge jumps in position, but hardly any blur. This suggests it was shot with a very narrow shutter angle.
The narrow shutter angle initially interested me as a possible explanation for why the streaks were sharp in some frames and not in others, but seems less relevant when the video is viewed and the flashing is seen in every alternate frame.
The title should be evidence enough, but the storyline seals the deal. Sure, it takes place in Halloween Town, but the story focuses on bringing Christmas into the world of ghosts and goblins. Watching it this year is particularly poignant as the film turns 30 years old since it debuted in 1993.
In the film, a zombie infection starts spreading during the Christmas holiday, quickly turning almost the entire town of Little Haven, Scotland, into a walking horde. This leaves a group of high school students to fight the undead.
Also, I have the best wife I could ask for. She keeps me in line while also being my biggest cheerleader and an inspiring mother to our children, who bring joy into my life on a daily basis, even when they push me to the brink of insanity.
So whether you celebrate the holidays looking at lights, snuggling up on the couch to watch a movie, or any other tradition you prefer, be sure to take stock of the blessings in your life. Cherish your time with those who are most important to you and have a merry Christmas.

It's interesting. I saw Lawrence of Arabia in 70mm on Saturday night, and I felt sure that it would rock my Cinematography Top 10. While the movie was just spectacular, and while it makes my Top 20 Cinematography for sure, I did feel that some of the scenes were overlit. Mainly these were the indoor scenes, but several times some of the outdoor scenes appeared to be overlit as well, to me. Way too much bounce back onto O'Toole.
I do realize that this is a product of the time in which the picture was shot. I also had the same exact problem with The Searchers.... While the outdoor, natural-light cinematography was flawless and amazing, as soon as they went indoors, many of the scenes were way overlit, IMO.
Is it fair to say that a turning point was reached with Days of Heaven, when Almendros agreed to the shoot the whole picture with natural light, aside from a a very small handful of scenes? Or were there pictures before DoH that really set the precedent for natural light?
Also factor in that movies were shown in drive-ins until the 1980's and the studios were constantly complaining to DP's that their dark photography would not play well in drive-ins, due to the lower screen brightness there.
Billy Fraker talks a little about this problem in the documentary "Visions of Light" (a must-see), how cinematographers like Gordon Willis went against the studios to do murky low-key photography like in "The Godfather."
Before faster-than-100 ASA film stocks came along in 1981-82, DP's had to resort to all sorts of tricks to shoot in natural light. There are plenty of examples that pre-date "Days of Heaven", just that that movie was nearly wall-to-wall natural light -- however, any "lit" scenes used electric lighting, like the locust plague (lanterns with light bulbs powered by batteries), or the few night interiors. So even that movie had artificially-lit scenes -- they just look natural:
But a movie like "Barry Lyndon" (1975) has a lot of natural-looking day exteriors and the candlelight scenes were famous for only using real candles (three-wicked candles, but real candles nevertheless.)
"Days of Heaven" was part of a growing trend of using less artificial light, it wasn't something out of the blue. Nestor Almendros had already been experimenting with those techniques in the 1960's, which is one reason why Malick hired him probably. It's just an example of taking this to an extreme. But there are precedents, as in the Swedish movies like "Elvira Madigan".
But David, do you hold the overlighting of movies like THE SEARCHERS and LAWRENCE OF ARABIA against the movie? Because frankly, I do. If you ask me what are the top 10 cinematography masterpieces, I have to admit that movies like Lawrence and The Searchers are overlit, while pictures like Apocalypse Now and The Thin Red Line are beautifully lit, with natural light.
No more than I hold anything against a Gothic painter for not understanding perspective. Movies are of their time -- you can't expect them to have the aesthetic standards of future generations. That's not fair.
