TerraBloom Ultra-Flexible Lighted Extension Cord

This extension cord is made of the durable compound TPE (Thermoplastic Elastomer), which can withstand extreme temperatures while maintaining flexibility. Amazon reviewers often complain about outdoor extension cords becoming stiff due to frigid temperatures. This flexible cord is an exception

It also features an LED lighted multi-tap (pigtail) design that allows you to plug in up to three strings of Christmas lights at the same time.

Coleman Cable Vinyl Extension Cord

This 16-gauge cord is UL listed and meets Occupational Safety and Health Administration (OSHA) requirements. It’s perfect to hang Christmas lights because the vinyl insulation resists oil, grease, moisture, abrasion and prolonged exposure to sunlight.

“Worked great,” says an Amazon reviewer. “Well insulated. I have it literally buried in my yard running to landscape lighting and the weather hasn’t bothered it.”

Milspec Direct Multi-Outlet Extension Cord

This Milspec Direct patented heavy-duty extension cord features Pro Cap outlets spaced at 10-foot intervals on the 50-foot cord. The outlet covers keep out dust, dirt and moisture. Each cord comes molded with lighted, transparent Pro Cap multi-outlet connectors and a ring-sealed male plug.

“This extension is awesome,” says one Amazon reviewer. “When placing inflatables in the yard for holidays it gives you spacing needed. Also, it is very durable and doesn’t need to be covered like a power strip needs to be.”
