It'd be nice if the OP's research had compared alternative forms of lighting to 'surprise' the oncoming driver, like flickering lights. This works well to draw attention both day and night (using less flicker). Given the continuing problem of drivers not seeing bikes, it's a shame it hasn't been adopted as the new norm for all bikes (and bicycle lights) -- both front and rear.
One of these crashes was right by my home, where I rode to work nearly every day prepandemic.
As a motorcyclist, at night, I wish I had the appearance of a car in other motorists' fields of view!
But if it means misjudging my proximity, sure, I do not want that. Still, I think a single point of light (common motorcycle config) gives even less depth information than a pair or triplet of horizontal lights. I've run two or three lights wide on most of my bikes for decades. ATGATT and fingers crossed...
I just don't ride at night.
$500 is about in line for a reputable kit that can hold up to the elements.

Mentioned in another comment but I rode at night when I was younger, but where I live there's just way too many drunk/aggressive drivers which is much worse at night, regardless of lighting situation. So I just don't ride at night.
