The red spot thing is the same general principle as the laser lane markers.
They might make you FEEL safer, but there's no data showing their efficiency.
Keep in mind that when the car gets close enough to matter, the driver will no longer be able to see the spot.
As for the lighted vest - as long as I have a decent lamp, I'm entirely happy with people using Hi-Viz, reflective vests.
I see them well enough, and have never found myself wishing for more.
A few lit lines like that, I'm not sure I'd see that as an improvement compared to reflective surfaces.
