Observed spectra of the night sky above Lick Observatory are presented, showing the light pollution due to lights in San Jose and other communities in the Santa Clara Valley. Spectra of several types of street lights are shown, and of these the low-pressure sodium lamp would cause the least additional light pollution if it were adopted for all future installations.
