I finish work at 8 pm so most of the year I ride back home in the dark wich I much prefer because the cars will give much more way than during the day. I have two 360 lumens light (only one one, the second as a back-up) and a rear blinkie but a LOT of reflective tape all over the bike. I feel pretty safe and , as i alway say, you just need one crazy lunatic on a cell phone to kill you no matter what time it is.
