Front headlights
Rear blinky
reflective triangle
reflective tape on crank arms
pedal reflectors
reflective tape on rims between spokes
tires with reflective sidewalls
I wear safety glasses almost 100% of the time, I have only one usable eye and want to protect it.
If riding at night I wear a reflective vest
when at night, I usually wear a helmet, with reflective tape stuck around it.
so, lots of stuff for night visibility, but not a lot more than that.
