Depends on conditions. Rear always blinking in the day on streets, off on bike paths.
Front blinking day or nite in urban traffic; steady hi on suburban/quiet streets or when
it's raining. On bike paths at nite; rear steady + front on steady and lowest output.

I myself use a hub generator and steady lights. Blinking lights confuse drivers ability to judge distance. That and pedestrians hate them.

I run 2 Hotshots on my commuter bike, and put them both on "random flash" mode during daylight hours. From dusk until dawn I run one of them on steady, and the other on slow-pulse mode. I alternate which one is on which mode to try to equalize battery life.

I run a Cygolite Expilion 700 front light on daytime flash during daylight hours, pulse mode during dusk and dawn hours (light stays on between pulses), and on steady when it's dark.

I use a Sanyo hub generator, a B&M tail light mounted to my rack, a Cygolite Hotshot clipped to my seat bag, a Philips Saferide headlight, and a SpokeLit spoke light in my rear wheel.

I wear a MET 20 miles helmet which has a reflective finnish and a taillight built-in, then I've got a pdw danger zone set to flash down on the rack. Up front, I use a pdw Lars rover 650 running solid, and I've got a collection of turtle lights from the mountain equipment coop just in case; 4 months per year, I commute both ways in darkness

Don't forget the reflective jacket. When headlights hit you from close distance behind, the reflective stuff is going to be a lot brighter than a taillight.

In my opinion annoying is good. It means you're being seen.
Here I ride with blinkie in rear and constant in front and keep all original reflectors on the bike (except pedals, I ride clipless) and ALWAYS wear reflective vest at night. But traffic on the highway here is bad and there is no shoulder to speak of.
Reflective tape is a must i.m.o if your bike is somehow without the original reflectors or you want to shed some weight.
I also ALWAYS wear a non-reflective safety-t during the day. Best way to go in daylight i.m.o.

I run two front and two rear, but one of each is on my helmet. Typically run my helmet lights solid, and my bike-mounted lights blinking.

On my helmet I've got a Planet Bike Blaze 2-watt micro, attached using their easy-to-use (purchased separately) helmet bracket, and the Planet Bike Blinky 3H is my taillight. I absolutely love having the Blaze on my helmet; it lets me see around corners and illuminate areas of the road I otherwise couldn't see, and it also lets me "flash" approaching drivers (by briefly shining the light on their car). This gets me a great deal of attention, and has helped prevent multiple problems at intersections. And if I'm feeling vulnerable, the Blaze's flashing pattern is incredibly attention gathering (though if I switch the Blaze to flash I run my other light solid).

Regarding bike-mounted headlights, I've been super pleased with my Cygolite Metro 300 - it's extremely bright for a battery-powered light, and drivers report that it seems as bright as a car headlight. It's also got a great flashing pattern that keeps the road illuminated while just varying the light intensity - attracts attention but still lets me see the road.

Lights, depends what time of day and where. Mileage on roads is not real big, I try to stay off them if possible. They are packed and ready for use of needed. Having issues with many of them, yes I have a few torches, they keep getting bumped turning them on. I do have lots of trails at my disposal and actually leave them off as much as I can. My living situation changed some and I now live in a different city and although I have ridden all these trails, I ride them so much more because of where I'm living. Having a good time riding them as well. I've picked up a new pass time, watching for the wild critters around my neighborhood. If my lights are on I won't see them if at all. Raccoons, coyotes, bobcats are all locals in this area. I've had coyotes 5 feet from the trail just standing there waiting for me to pass so they can run to the other side. When I turn some lights on they suddenly look up in amazement that they have been seen and bolt. Seeing them often you get to hear them as well. More and more curiosity for me. Different howls and barks. Bobcats I don't see as much. They see or probably hear you first and are gone by the time you pass. I tend to always be pedaling even when breaking, no sound from the cassette and squeaky sounds really bug me so the bike is real quiet. Raccoons are the bulk of critters. A church group about a mile away lures them in with 4 dumpsters that happen to be close to the trail. Saturday's can be funny, I've counted 21 I think on a Saturday night. I swear they can tell time. For birds, I think there are 5 nesting pair of osprey not that far away. Some owl can be heard, if your lucky maybe even seen. A nearby golf course has geese and other birds, the Egyptian geese are around and are neet to see. Roadrunner are also in the area. A new thing I discovered hiding in plain view are bats. A section of trail goes under a main road with maybe 15 feet above you. Something clicked one day and I figured it out. The 15 feet gives you a real close look. It also has since told me that those are not birds that are always flying at night.

So, I have lights and use them sometimes, when needed. Other riders I see ahead coming I alway turn on a small strobe to be courteous.

Hello everybody, my name is john and I'm a flashlightholic.

For a tail light I have a CatEye unit that blinks or stays steady, I keep it steady at night. For a headlight for now I taped a Coleman LED head light (that is worn around ones head, I removed the headband) to the handlebar. It has a high and low white LED or two small red lights all steady.

Starting at the top:

LNM Vis 360 (pulse morning steady night)
LNM 550 (night only steady)
PB Blinky 5 (Steady night)
PDW Fenderbot (flash night)

I also have a ton of side reflection from my tires and I bought some sunlite large wheel reflectors off amazon a while back. My pannier is reflective and so are the zipper pulls on my pannier along with the framebag.

Day time near traffic - slow blink front and rear
Day time path / off road - none unless it's grey, rainy, or foggy, then slow blink front and rear

Night near traffic - solid front blinking rear
Night on path or off road - solid front and rear

I also wear a reflective vest at all times near traffic day or night, and sometimes on busier trails and paths - gives that extra bit of visibility.

Day time: Flashing battery powered front light and tail light.
Night time: Solid battery powered front light and flashing tail light.Plus I am using an old fashioned dynamo powered front and tail light. But I am getting a new LED Busch an Mueller Cyo light this weekend to replace my Halogen light.
In addition I am wearing a jersey in safety colors with reflecting stripes. When its getting colder I will switch to a jacket with safety vest on top.
And then I plastered my bike with reflective pin stripping this weekend. Although the reflection on the frame looks orange with the flash it is actually red. The stripes on the fenders are black and will reflect white. But I don't care. I just want to be seen. No matter what color.
