There are places in downtown Lima, i think on Abancay that sell all kinds of lighting and I have seen similar items. Right now they have lots of Halloween decorations, but I am sure you could find the lights you need.
Its a little nuts, but pretty safe in the daytime. You need to go to the Calle Capon with a market called the Bario Chino.
On google maps look for Andahyalyas and Jiron Ucayali: https://www.google.com/maps?t=m&ll=-12. ... ut=classic
You probably should go with someone who knows the area. There are ALL kinds of lights stores around that part of town.
