I work 5-11 P.M. Lights and a reflective vest are my best friends.

One time I worked a shift from 6 PM to 6:30 AM... after 12.5 hours, the 90 minute ride home was difficult.. In the winter time, I enjoyed the sense of sunrise/ sunset being near both ways.

Jail!

OK, probably not. I've had to run red lights on my motorcycle because the sensors wouldn't detect that bike. I'm sure my bicycle would be worse.

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.

Commuting at night
 

I only commute in the dark when we run out of Daylight Savings time, but I do enjoy riding in the dark. It's an entirely different experience. I went out to dinner last night & Rode home in the dark. It's very enjoyable.
