Many countries (not the US of course) require auto-mobiles to have daytime running lights as it has been long ago proven to be effective in reducing accidents.

"Because the human eye is light-seeking, drivers will see an oncoming car sooner and make a more accurate estimate of its rate of approach. The effect is particularly important for peripheral vision, which may not see an object at all unless it contrasts sharply with its background or moves against it. Using daytime lights significantly reduces the chances of a car, cyclist or pedestrian moving unexpectedly into your path."

As such, my sense is that it would logically follow that a bicycle with a daytime running light would also reap a similar benefit.

I have been riding with daylight lights front and back for about 4 years now. (Currently, Dinotte 1200L+ in the front on high and the Dinotte 140L flashing in the back) I'm sure it helps me be seen by motorists much earlier than not having lights on at all.

I run a Busch & Muller dynohub generator light. I got it on deep discount and it ended up being defective in a kind of cool way -- I can't turn it off! So I have a daytime running light always. I started flashing the rear ones as well. It only seems silly when I'm riding on trails, on the road it's fine.

One thing I notice doesn't get mentioned much is shade. Cyclists or pedestrians (or dogwalkers) can sometimes get lost in shady sections of a road. Lights are our friends.

Since the majority of my riding takes place in early morning or late afternoon, when the sun is lower, lights on the rear would just blend into the glare. (Unlike most, when I was driving and encountered a high-glare, low-viz situation, I would slow down, being unsure of what was in front of me.) More light added to an already-intense light blitz like that is, to me, useless.

Midday, on fun or utility rides, is different; overhead sunlight creates less glare.

I do see the advantage in light-to-shadow transitions, though.

There may be a couple of reasons why we would notice different behavior with and without lights. First is visibility... drivers are simply more likely to see you. Second is the perceived behavior of the cyclists in the eyes of the driver - nothing pisses off motorists (and lots of cyclists) more than an irresponsible cyclist, and seeing a cyclist responsible enough to use a light/reflectors/safety equipment while riding predictably and safely on the road will likely get more respect from some motorists.

My strategy is to have enough reflectors and lights that if I get hit it won't be an accident.

I have heard this argument before and I don't buy it. THe mind and the eyes do not pick out areas of lower light as significant. If there is a lot of glare then get a brighter or more obnoxious light. That's my take anyway... you, of course are free to use or not use lights whenever you wish, and I wish you safe and happy riding always

I don't use a rear blinkie and some days the give me lots of room and some days they don't. I almost always wear the bright orange jersey in traffic though. My guess is that it depends on who is out on the road that day and not the blinkie.

Some days I do wonder why every driver seemed to be so courteous.

Maybe for you, but when I have to cross about a half-dozen of these on my way to and from work in the early morning and late afternoon, the blinkie works:
