Beautiful lighting but stops working after light rain

I bought these twice because the first two strands stopped working. They are not water proof or weather proof! I love the color, the soft lighting, the length is perfect, but they stop working after it rained once...this happened both times. I thought maybe something happened to the first two strands, strung across our fence. Then I bought two more strands that stopped working after one light rain. Not feasible to take them down and put them back up after each rainstorm. Where can I get better lights?
