To be honest, I'm not sure Conde's story is likely to be part of the explanation for the Rendlesham Forest events.
But if it
were, perhaps the easiest possible "field modification" he might have performed (lighting mounts allowing) would be to tip back a lightbar/ beacons 90 degrees so their beams rotate in the vertical, not horizontal plane.
Hey presto, lights go up and down in the mist. -Admittedly speculation on my part.
Pretty much all cars have a hazard light function, where all the (amber, orange) indicators flash simultaneously.
Some US police cars have red, blue
and orange lightbars, don't know if this applied to any USAF SP cars in 1980.

(IIRC there are others in red-white-and-blue with much shorter amber lights at each end).
Again, I don't know what US SP cars might have routinely carried; I do know that 1980s British service police vehicles often (depending on role) carried a few battery-powered amber beacons a bit like (not the same as) this, which could be set to flash.

(Edited to add; British service police vehicles also sometimes carried
Bardic lamps, with a rapidly-switchable red-green filter; wouldn't be surprised if USAF SPs had similar. Or perhaps some fancy attachment for their Maglites

).
Well, they can't all be completely accurate, can they?
If it's a cover story, it's crap.
Instead, it reads like the recollections of people who had seen quite difficult-to-discern lights, and who tried to make out their colours (if any).
We have to accept that the airmen on the 26th (Burroughs, Cabansag, Penniston) were following pretty much
any light they saw- that's why they ended up at one point looking at a farmhouse with its lights on, and finally ended up looking at a lighthouse. As per their statements.*
They could not have been in constant visual contact with a single lightsource.
@JMartJr gave an excellent example
(post #412) of three policemen and a magistrate describing a sizeable (not a point) light in the sky, one describing it as rectangular. Other witnesses said it shined down on them. It was Venus.
Jimmy Carter probably saw Venus.
External Quote:
It was big, it was very bright, it changed colors and it was about the size of the full moon. ...seemed to move towards us from a distance, stop, move partially away return then depart."
Post #407 has examples of police officers in Georgia and England pursuing Venus- in the latter case it was sort of cross-shaped, radiated beams of light, stopped in a field and acted as if it knew it was being chased.
I don't believe any of those witnesses were lying. I doubt if any of them were inherently unreliable witnesses.
It is possible that all, in each case, gave as honest and accurate account as possible.
But all were very likely mistaken, and the descriptions they provided probably do not describe what was objectively visible.
For whatever reason, all interpreted something reasonably mundane as something unusual.
*Penniston told Chandler that the lighthouse was not what he had seen in the forest. Even if he believed that, omitting the lighthouse from his (Penniston's) statement must be highly questionable, and perhaps an early red flag. They had gone out to investigate lights, and ended up looking at a lighthouse. That fact is pertinent, even if Penniston didn't like it. Instead, it looks (to me) like Penniston didn't document the lighthouse because he didn't like the conclusions that others might have drawn from that information.
