Connect input drive signal to ULN2803 input pin. Connect lamp between the corresponding output pin and +V. Connect pin 10 (COM) to +V. In Proteus, the common emitter pin of ULN2803 is hidden and is connected to ground.

By the way, for driving a single lamp, you can just use a transistor. You don't need to use ULN2803.

Hope this helps.
Tahmid.
