Christmas window icicle lights – 3 ft UL‑certified string

Christmas window icicle lights are a 3‑foot UL‑certified string of 50 warm white bulbs that can be used on windows, archways, roof lines, staircases or railings. The set includes a white wire, two suction clips for easy mounting, and a safety‑fuse plug, making it suitable for outdoor holiday decoration.

The lights offer two modes—steady on or flashing—and feature a string‑to‑string connector that lets you join up to ten sets for a longer display. If a bulb fails, the remaining bulbs stay lit, and the package provides two flasher bulbs, two regular replacement bulbs and a spare fuse. The design is waterproof and weather‑proof, and the spacing between drops and bulbs creates a random icicle effect.

These lights are marketed toward professional decorators and work well in smaller spaces or as fill‑ins, thanks to the 3‑foot span and 3‑inch drop spacing. They are pre‑tested and come with a warranty that the lights will function as intended.
