I don't have any data to backup my opinion but I think dawn and dusk are the worst times. The low sun blinds drivers and lights have a hard time to compete with sun. At night with decent lights a bicyclist can be quite visible.
Even during the day time there are dark spots (often shade from trees on bright days) where a cyclist can disappear.
For those situations I installed Reelight blinkers on my bike. The light isn't as bright as I'd like but once installed you can forget about it. Hub generator of course would be nicer. I forced these lights upon my kids as well. So with a little luck these lights make a difference. For (potential) night riding I do recommend additional and brighter lights.
