Majority of my commuting and errands between November-January is done in the dark. I leave my home at 6:00AM in the morning and get back home after 6:00PM. I am looking forward to late January and February when days start to get longer. I use lights when riding on the road, but whenever I ride along wooded MUPS lights get turned off and I prefer to be stealthy, I also wear dark coloured clothing.
