I use pretty inexpensive lights up front that flash, and a red blinkie, also inexpensive for back. The 2 cheap flashing lights in front, one on the handle bars and the other down on the fork, provide enough light for my unlit MUP.

Soon you won't need any lights for the ride home, if it isn't already light out now.

The more reflective you and the bike are, the better your chances of not getting run over when you are off the MUPs. You can get a lightweight and inexpensive reflective vest. I have one that I can wear without a shirt when it's warm and it stretches enough to fit over layers, even with a jacket when it's cold.
