Final answer:
Lissa needs a two-way switch to control her bedroom light from both near the door and near her bed.
Step-by-step explanation:
Lissa needs a device called a two-way switch to control her bedroom light from both near the door and near her bed. A two-way switch allows the control of a single light fixture from two different locations. This is achieved by using a combination of two switches and a traveler wire. When one switch is turned on, the circuit is completed and the light turns on, and when the other switch is turned on, the circuit is broken and the light turns off.
