Some black‑wire icicle sets are constant/steady only, while others offer multiple modes. Example listings include 3‑setting sets and one set showing 8 modes (one of which is multicolor flashing). Check the product listing to see whether a set is single‑mode or multi‑mode.
Most listings are electric plug‑in (mains) sets. At least one listing is battery powered and specifies it requires 2 AA alkaline batteries (required, not included).
Listings include indoor‑only, indoor/outdoor, and sheltered‑outdoor designations. Some sets are explicitly UL certified or UL listed for indoor and outdoor use.
Both LED and incandescent bulbs appear in the listings. Colors shown include orange, multicolored, clear, and purple.
