There's a huge gap between the two.
I don't have a vest but I did the next best thing - orange and prismatic tape on my backpack. I have a light on my helmet as well as front and rear lights on my bike. Any time it is suggested or mandated that motorists have their lights on (rain, an hour before dusk, etc) my front light is on steady and my helmet and rear lights are blinky.
Things I've seen on others that I think are reasonable for safety and want to do are additional spoke reflectors that have bright multi-colored lights for nighttime use and individual green LEDs that a motorcyclist had both on his motorcycle and his person (I counted 6 total).
Crossing into paranoia was getting my will signed at work and sticking it into a plastic bag so the writing wouldn't be obscured by blood in case I got hit going home. Making oneself as visible as possible is common sense, not paranoia.
