Even though the button is now animated, the screen must clearly display when the lights are on or off.

The screen designer:

1. Inserts a rectangle object in the reservoir group.

2. Opens the rectangle object's Properties dialog box.

3. Enters expressions that use the variable {LIGHT} to apply color animation to the rectangle.

A	{LIGHT} EQ 1	Turns the lights on.
B	{LIGHT} EQ 0	Turns the lights off.
