LED icicle lights are pre-wired Christmas light strings that hang from gutters and eaves in an icicle pattern, using 80% less energy than traditional incandescent and connecting up to 45 sets end-to-end. Available in M5 and 5mm wide-angle bulb styles, warm white, cool white, multicolor and other colors, plus SoftTwinkle® light display.
LED Icicle Lights for Outdoor Displays
Our LED icicle lights are rated for outdoor use and built to withstand rain, snow, and temperature fluctuation across multiple holiday seasons. LED bulbs are sealed components with no filament to burn out — rated for up to 100,000 hours — and UV-stabilized for long-term outdoor exposure. They remain cool to the touch during operation, which makes them easy to handle while adjusting your display.
For long roofline runs, the end-to-end connection count of LED is a meaningful practical advantage. LED icicle lights connect up to 45 sets on a single outlet, compared to 3–6 sets for most incandescent sets. One strand covers approximately 7 linear feet of lighted length — enough to plan a full roofline run from a single outlet without an extension cord nightmare.
Which LED Icicle Light Bulb Style Is Right for Your Display?
LED icicle lights come in two bulb styles with distinct visual characteristics.
5mm wide-angle bulbs feature a concave, inverted-cone lens that captures light and projects it outward in a bold starburst. They're the right choice when you want maximum brightness and visibility from the street. 5mm wide-angle is also the only style available with SoftTwinkle® slow-twinkling icicle lights.
M5 bulbs have a diamond-faceted finish that produces a brilliant sparkle — a more classic look that bridges the feel of LED and traditional incandescent aesthetics. Our color-changing icicle lights are available in M5 only.
A snowflake-lens option is also available in cool white — with a shaped lens that adds a wintry, decorative touch to the standard icicle drop.
What Colors Do LED Icicle Lights Come In?
The most popular colors are cool white and warm white LED icicle lights — cool white for a crisper, more wintry appearance, warm white for a soft, candlelight look.
For more variety, LED icicle lights are also available in multicolor and a range of specialty color combinations, including blue-and-green, green-and-red, and cool-white-and-red (all 5mm only). Halloween displays are well served too, with an amber-and-purple option available on black wire (M5 only).
Twinkle LED Icicle Lights: SoftTwinkle® and Traditional Twinkle
SoftTwinkle® LED icicle lights are a 5mm wide-angle option where each bulb fades in and out at its own rhythm — no synchronized flashing, no rapid strobe. The visual result is a slow, organic shimmer along your roofline, similar to embers or distant stars. SoftTwinkle® is available in warm white, cool white, multicolor, green-and-red, and cool-white-and-red.
Traditional twinkle icicle lights blink on and off abruptly — a distinct look from SoftTwinkle®'s fade. Traditional twinkle is available in warm white and cool white, in both M5 and 5mm wide-angle.
Pro Tip
All-In-One clips let you display LED icicle lights and C9 string lights along the same gutter at the same time. Each clip has a hook for the icicle light strand and a clasp for a C9 (or C7) bulb. At 4.8 watts per LED icicle set and 0.8 watts per OptiCore LED C9 bulb, most homes can power a full combined roofline display from a single outdoor outlet.
Cool white or warm white LED icicle lights — which looks better outdoors? This depends on the look you want. Warm white produces a soft, classic glow that recreates the look of traditional incandescent Christmas lights. Cool white produces a crisp, bright look evoking ice and snow.
How do I hang LED icicle lights on gutters? Snap Christmas light clips onto the lip of the gutter — no tools or nails needed. Space clips 6–12 inches apart, starting from the end nearest your power outlet and working outward. Before hanging, gently tug each drop from top to bottom to help it reach full length — drops are packed tightly and will appear shorter than the listed measurement until they relax. One strand covers approximately 7 linear feet of lighted length.
How many LED icicle lights can I connect end-to-end? LED icicle lights connect up to 45 sets end-to-end from a single outlet. At approximately 7 linear feet of lighted length per strand, that covers approximately 315 linear feet from one outlet — enough for most residential rooflines without a second circuit. This compares to 3–6 sets for most traditional incandescent icicle strings.
How long do LED icicle lights last? Our LED icicle lights are rated for 100,000 hours. LED bulbs are sealed components with no filament to burn out, and they don't degrade from heat the way incandescent bulbs do. At typical holiday-season use, that rating translates to decades of displays from a single investment.
What's the difference between M5 and 5mm wide-angle LED icicle lights? Both are LED, but the lens style differs. 5mm wide-angle bulbs have a concave inverted-cone lens that broadcasts light outward in a bold starburst — the higher-visibility option, and the only style available with SoftTwinkle® slow-twinkling. M5 bulbs have a diamond-faceted finish that produces a brilliant sparkle and a slightly more classic look.
What makes LED icicle lights professional grade? Professional-grade LED icicle lights are built with sealed, one-piece bulb housings that keep moisture out and shatterproof acrylic lenses that handle installation, removal, and storage without cracking. They're rated for 100,000 hours of use — far beyond standard residential LED strings — and carry a UL certification for outdoor installation.
What wire color should I choose for LED icicle lights? White wire is standard for most LED icicle light installations along gutters and eaves — it blends with white fascia and trim and disappears against most gutters. Green wire LED icicle lights are a better choice where the wire runs against wood, foliage, or natural structures such as pergolas and fences. Black wire is also available on select M5 sets, including the amber-and-purple Halloween option.
What's the difference between SoftTwinkle® and traditional twinkle LED icicle lights? SoftTwinkle® icicle lights work differently from traditional twinkle: each LED dims and brightens independently, with no abrupt changes. The result is a living shimmer across your roofline — subtle, continuous movement.
