There are two big masses of lights, one off the coast of Peru and one off the coast of Argentina, that aren't connected to any landmasses whatsoever. Look 250 km W of Barranca (which is north of Lima on the Peruvian coast), and for the rest, start with the Falklands and look for a cluster 100 km north, one 150-200 km northwest, and one 100 km west.
The cluster off of Peru might be displaced from the Ecuadorian islands to the north -- the shape looks vaguely similar to the islands Isabela, Fernandina, Santiago, Santa Cruz, and San Cristobal (at around 0 deg N, 90 deg W).
I suspect the cluster near the Falklands has been displaced about 300 km to the southeast -- the "ring" just north of the Falklands matches the area around Comodoro Rividavia, the western cluster matches Isla Wellington, and the northern inverted-Y shape seems to roughly follow highways 26/40 in the western part of south Argentina.
EDIT: I moved around a bit more and noticed there are lots of faint streaks off of the coasts of South America, including a fairly big blob just east of Rio. I don't know whether it's browser-specific or something screwy on the backend.
EDIT 2: while most of my local area (Denver) looked sane, I noticed a bright cluster near Hereford, CO (around 41 N, 104 W) and that's just pure farmland. The map shows [0] in the middle of a fairly heavily light-polluted area.
