My shift ends at 11:30 so like the OP, I am a late night commuter. I have found that a Cygolite Dash 320 on the bars and a Cygolite Hotshot SL on the rear is a great setup. I ride a combination of city streets, neighborhoods and a pitch black MUP. On the city streets that are lit, the Dash 320 is on bright blink mode so I can be seen. As soon as I hit the neighborhoods it goes to the second brightest solid setting. For the MUP, the brightest solid setting which is ample light to see well ahead and to the sides into the brush and trees. Both are USB rechargeable and have held up extremely well so far through all kinds of weather conditions, especially the Dash 320.
