an emergency flasher weakly lighting the alternate LEDs at an HF rate.

On review of the circuit (having neglected the capacitors) it looks
more like a lower rate in a somewhat haphazard logic race of a
relaxation oscillator whose RC (1K-101K times 0.01µF) still makes this
wobbulate at higher than visible rate (or lower than perceptible
brightness, take your pick).
