What do the flashing LEDs mean?

Switch set to USB/OFF

Green LED lit continuously - connected to computer

Red LED flashing for up to 2 seconds - Battery power indication.

When the switch is set to USB/OFF the red LED will flash from 1 to 4 times depending on battery voltage, with 4 indicating full. Please replace the batteries if the LED flashes only once or twice, as they will not have enough power to last the night. If the battery voltage is below the minimum threshold the red LED will flash rapidly for about 2 seconds, and you should replace the batteries immediately.
