Here's an explanation from our web page about the Baker Library bell tower <http://www.dartmouth.edu/~library/bakerberry/general/bells.html>:

ABOUT THE GREEN LIGHTS

Every now and then, a green light shines from the tower on Baker Library. The green comes from energy efficient green LED lights that shine on the glass windows in the bell tower.

This green light is often referred to as the "money light" because it is lit on occasions that attract College alumni and trustees.

In October 1975, Jack Skewes, then Director of Business Affairs, wrote a memo listing the events during which the "green lantern" would be lit. The same events trigger the green lights today. The memo reads:

Green lantern lit in Baker Tower:
Convocation (when held in the evening)
Dartmouth Night
Winter Carnival Weekend
Class Officers Weekend
Freshman Parents Night
Greenkey Weekend
Reunions
Commencement
Club Officers Weekend
Alumni Council Weekend
Trustees Meetings
Fall House Parties
