I bought two boxes of 4 each Hampton Bay #498-959 Solar Garden Lights at Home Depot. After about two years operation, the translucent plastic housing became brittle and fell apart. This plastic is not sunlight resistant! I wrote to Home Depot a complaint, but got no reply. For those who would like to know how to Hack a solar light and use them for other purposes, here is a pdf of the construction. Perhaps you should wrap aluminum foil around the translucent plastic housing to keep the sunlight from destroying the plastic.

Build yourself a electronic candle that is safe from fire. I found a great program to load in a 12f675 PIC microcontroller from a website named Mondo Technology. I changed the circuit to allow using a mosfet to flicker a 12 volt light bulb to simulate the candle. I mounted the bulb inside a glass star to complete the effect.
