My 5-yr old daughter was so excited when her Twinkling Light-Up Witch Costume arrived in the mail. She was crushed when it quit working shortly after. We changed batteries as a first try. When it became clear that didn't work, I began tracing the wires to the light source. I pulled the light component from the little pouch and gave it a few short strategic bursts of DeoxIT Gold. To my amazement, a few seconds later -- a fully functional Twinkling Light-Up Witch Costume.
