Yes, left turning cars are my primary fear as a rider. Of course the problem arises during the day too, not just at night. 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.
