I think the science here is so weak, people should probably just go with their non-scientific conclusions.
I'm looking at it from a driver's perspective, and those lights don't usually stand out any more than the guy I might hit would. Flashing lights are great at drawing my eye to the bicyclist completely on the opposite side of the road from me on the left which is probably the position I'm least likely to actually cross paths with them.
