According to reviewers, make sure you remove the bulbs first and hang just the wire, to prevent breaking the bulbs. Once the wire’s secure, then screw the bulbs back in! I did this in a yard once and it worked really well. 

Each bulb socket has a clip on it to make for easy hanging/securing. And they’re waterproof, so you don’t have to worry about rain. Cable ties or screw-in cup hooks would work well for installation! You can get them with either a white, black, or green cord and sockets, so you know they’ll match your house, trees, or decor. 

Promising review: “I had a set of these on my patio for a good 3–4 years. They were totally exposed to the elements. Sun, heat, rain, etc. They only recently failed. At this price, I had no issue with replacing them with a new set. It cost less than buying a new fuse and a few replacement bulbs. And now I have plenty of extra bulbs from the old set.” —CA Buyer

Get them from Amazon for $18.99+ (available in three lengths).
