The most effective method of conspicuity for side and turning conflicts is a visible headlamp on the bicycle, as the reflectors aren't generally in the beam pattern and an emitted beam that reaches the conflicting driver's eyes is needed.
I actually put reflectors on my first two touring bikes. I built them up, thus reflectors did not come on them. Yes, I even paid money to buy reflectors. BUT, they were cheap reflectors, and not made very well, they did not reflect very well at all. I eventually chucked them.
All of my touring bikes (three) have reflective sidewalls when I tour. Yes, a reflective sidewall does not move like a reflector moves (it moves, but the reflected light is from the same place as if it was not moving), but it still is quite effective and even though part of it is hidden behind panniers, part of it is always visible.
