When night falls how do you roll? Do you set your headlight on blink mode or steady? Do two or more lights light up your way?

I ask because a cyclist I know here in MN told me that having your light set to blinky mode after dark is illegal. He thinks that blinky mode is for daylight or twilight hours while steady mode is for the deep of the night.

Thoughts?

I, for one, go back and forth. On MUPs after dark I go steady and have it on a lower setting so I don't annoy other cyclists. On roads (generally) I like to have the strobe effect going. Maybe it's a fantasy, but I feel more visible and safer.
