Query: I feel a lot less invisible at night

I'm a bike commuter who works second shift. Some of the roads I ride have no sidewalks or street lights. I really, really want drivers to see me. This vest has been extremely effective. Turning on the lights was a bit tricky at first; the switch on the battery box has to be on before you can use the button on the outside of the vest. I'm not a thin woman, but it fits comfortably over my jacket (I had to get creative to fit it over a backpack). I feel a lot less invisible riding home.
