I leave my house 5:55AM.
That allows me to go through a sensored traffic light while it's still on caution. It blinks caution from midnight - 6AM. Even though it's legal for a bike to run that traffic light when holding red, I prefer to leave just early enough to avoid it.

When I first started commuting via bike, back in May it was daylight. For about two weeks it's been completely dark when I leave. I bought an extra set of lights (2 front and back) plus the reflective vest. I'd like to add a bigger front headlight for lighting up the street and run both of my existing front lights as flashers.
