The answer is:
android:background="@android:drawable/btn_default"
For example, the following will cause the light to disappear, and the toggle button will look like the default button, but with a toggle function:
<ToggleButton android:id="@+id/your_btn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textOn="On" android:textOff="Off" android:background="@android:drawable/btn_default" />
