I have to ride on narrow, relatively busy, 35mph-limit rural roads with no street lights to get to school. I run a superflash in back and an Ultrafire 606a from dealextreme on my helmet, along with reflective tape on my rims, seatstays, and fork. So far I've had no problems and it seems pretty safe, but I can't really say for sure - many bike ninjas and wrong-way riders have never had any problems either.
