Flip the switches to turn off the lights - it is harder than you think!

The goal of De-Lite is to turn off all of the light bulbs. Unfortunately, the electrician that setup the light switches had far too much free time, and has made a bit of a mess of the wiring.

Each switch on the left is connected to only some of the light bulbs. The connected bulbs for the switch are indicated by a X in the switch row. When the switch is flipped, each connected bulb will change state: if it was on, it will turn off, if it was off it will turn on. The right combination of switch states will turn all the bulbs off.
