Outdoor Christmas Lights
The best Christmas lights for windows, outside
A window is a small, square, close-viewed object with no outlet anywhere near it. Those three facts rule out most of what works on a roofline.

The short version: for outlining a window frame from outside, buy 5 mm wide-angle LED mini lights on green or brown wire. Their 4-inch bulb spacing is the only common spacing that reads as a continuous line on a run as short as a window. If the window is on a second story or above a porch roof, hang icicle drops from the head casing instead. If there is no outdoor outlet within reach — which is the usual case on a bedroom window — a battery set with a built-in timer is the honest answer, not a 50-foot cord.
Why window lights are their own problem
Every other outdoor run on a house is long and far away. A roofline is forty feet of light read from the curb. A window is eight to sixteen feet of perimeter read from the driveway, the sidewalk, or sometimes from two feet away as somebody walks up the path. Three consequences follow, and they decide the whole purchase.
- The run is short. A single 24-foot strand usually covers one standard double-hung window frame with slack to spare. Buying a 78-foot set for a window means coiling 60 feet of wire behind a shutter.
- The viewing distance is close. A C9 bulb an inch and a quarter across, set six inches apart, looks like a string of streetlights on a window casing. The same bulb on a gutter line forty feet up looks right.
- There is rarely an outlet. Exterior receptacles are near the front door, the garage and the deck. They are almost never under a window.
Spacing: the number that makes or breaks a frame outline
Industry spacing guidance scales to what is being lit. 1000Bulbs gives 6 inches as the maximum bulb spacing for a tree, gutter or house trim, specifies a tighter 4 inches for poles and banisters, and goes down to 2.5 inches for wreaths. A window casing is closer to a wreath than to a gutter — it is a small frame you look straight at — so 4-inch spacing is the right target and 6 inches is the upper limit before the outline starts reading as dots.

The four ways to light a window, and who each is for
- 1
Outline the frame
A continuous run around the outside of the casing — head, both jambs, sill. The cleanest, most architectural look and the one that reads best from the street. Needs the tightest spacing and the most careful corners. Roughly twice the height plus twice the width of light per window, plus 10 percent for the four turns.
- 2
Icicle drops from the head casing
Drops hanging down over the glass from above the window. Extremely effective on an upper-story window where the drops have air beneath them, and the fastest of the four to install. Less good on a ground-floor window where the drops hang in front of somebody's view out.
- 3
Net light over the glass
A single panel of light across the window, held at the corners. The quickest method by a wide margin and the most forgiving of a crooked frame. It reads as a lit rectangle rather than an outline, which suits a garage-side or gable window better than a front window.
- 4
A wreath or a single accent in the sash
Not a light run at all. On a window you cannot easily reach or power, a lit wreath hung centre-pane is the right answer and is why pre-lit battery wreaths exist. Covered in best outdoor Christmas wreaths.
Attachment: the part people get wrong
A window casing is painted wood, vinyl trim or clad aluminium. None of it takes a gutter clip and none of it should take a nail or a staple. There are three workable options and each has a condition attached.
- Adhesive hooks rated for outdoor use. The standard answer on a smooth painted or vinyl casing. The condition is temperature: outdoor adhesives specify a minimum application temperature, so these must go up in mild weather and be pressed onto a clean, dry surface. See clips vs adhesive hooks.
- Vinyl siding hooks for the run between windows, if the casing is set into vinyl. They slip into the seam and hold without a hole — the same hardware covered in best Christmas light clips for vinyl siding.
- Cup hooks screwed into the casing, which is permanent and the right trade on a window you will light every single year. Eight hooks per window, done once, turns every future December into a ten-minute job.
- Never a staple through the wire. A staple that nicks the insulation on a window run is both the most common cause of a dead strand and a genuine hazard at hand height.
The no-outlet window, answered honestly
Most windows on a house have no power. Running a cord up a wall to a bedroom window to light eight feet of casing is a bad trade — it is visible in daylight, it is a trip and water hazard at the bottom, and it burns a receptacle you need for the rest of the display. A battery set is the correct answer here and windows are one of the few places it genuinely is: the run is short, the battery box tucks behind the casing or inside the sash, and most sets include a 6-hours-on timer so you are not switching eight windows by hand every night.
The limit is cold. Alkaline cells lose most of their usable capacity below freezing — see how long battery Christmas lights last for the figures and the lithium fix. Expect fewer hours than the packaging claims, and plan on one battery change mid-season.
Inside the glass or outside the casing?
They are different purchases and people conflate them. An indoor-mounted set sits in a warm, dry, UV-filtered environment and can be a thin indoor strand on clear wire. A set on the outside of the casing takes freeze-thaw cycles, wind-driven rain and direct sun, and needs to be rated for outdoor use with a wire colour that disappears against the trim. If you are buying one set to do both, buy the outdoor one.
How many feet to buy
- Measure one window's casing on the outside: head plus sill plus both jambs. A standard 3 x 5 ft double-hung is about 16 ft of perimeter.
- Add 10 percent for the four corners and the slack lost at each turn — the same allowance the Emporium's method applies to a whole house.
- Multiply by the number of windows you are actually lighting, then round up to whole strands: a 24-foot strand covers one window and a bit.
- Decide where the run starts. If you are chaining three windows on one plug, add the gap between them to the total, and check the end-to-end connection limit on the tag — see how many lights on one circuit.

Top pick
5 mm Wide Angle LED Mini Lights, 70 ct, green wire
Wintergreen Lighting
The commercial 5 mm wide-angle string is the format built for tree wrapping: a small concave lens that throws light sideways, on a green wire that disappears into bark and foliage in daylight.
Wrapping a tree is a different lighting problem from outlining a roof, and the bulb that solves it is different too. A roofline wants a big bulb that reads as a distinct point from the street. A trunk wants a small bulb, close together, that turns the bark into a glowing column — and that is what the 5 mm wide-angle format is for. Christmas Lights, Etc identifies 5 mm LED wide-angle lights as the type most commonly used on outdoor trees, and the reason is the lens: it is concave, so it spreads light sideways around the curve of the trunk instead of firing it into the street.
Wintergreen's 70-count set runs 24 feet on green wire. Green matters more than people expect. Lights are lit for roughly eight hours a night and the wire is visible for the other sixteen, and white wire spiraled up a dark trunk is a barber pole in daylight. Green disappears against bark and evergreen foliage; brown wire, sold in the same format, disappears against deciduous trunks.
The practical limit is length. Twenty-four feet sounds like a lot until you wrap it: at the 6-inch spiral spacing Christmas Lights, Etc recommends for the best look, a single set covers a surprisingly short stretch of a mature trunk. Buy by measured length rather than by set count, and buy connectable so the whole trunk runs off one feed.
What you give up against a socketed C9 is repairability — these are prelamped, so a failed section is a failed set. For a trunk wrap that is an acceptable trade, because the wire is doing structural work around a rough surface and the failure mode is usually abrasion rather than a dead bulb.
What works
- Wide-angle lens spreads light around the trunk rather than straight out
- Green wire is invisible against bark and foliage during the day
- Connectable, so a tall trunk is one continuous wrap from one outlet
- Small bulb means the wrap reads as a line of light, not a row of dots
What does not
- Bulbs are not individually replaceable on a prelamped set
- 24 ft per set covers less trunk than you expect once it is spiraled
- Manufacturer does not publish a rated-hours figure for this line
| Bulb | 5 mm wide angle (concave lens), LED |
|---|---|
| Set | 70 bulbs, 24 ft |
| Wire | Green (other colors sold in the same line) |
| Use | Commercial grade, outdoor |
| Connectable | Yes, end to end |
Gutter lines and porch eaves
Toodour LED Icicle Lights
Toodour
Varied-length drops off a horizontal wire. The look only works on a genuinely straight run, which is why they belong on a gutter and almost nowhere else.
Icicle lights are the one light type where installation quality is nearly invisible. The drops are deliberately different lengths, so a clip line that is a half-inch off here and there disappears into the design. On C9, that same error is a visible sag.
That forgiveness only applies on a straight horizontal run. On a raked gable — a roof edge that climbs at an angle — icicles hang vertically off a sloped line and the effect reads as a mistake. Gutter lines, porch eaves and the horizontal band above a garage door are where they work.
Storage is their real cost. The drops interlock with each other in a box, and untangling a set of icicles in November is a genuinely unpleasant hour. They are the strongest argument on this site for buying a storage reel, which is why we link that section from here.
Toodour's sets come in the three standard colors and are connectable, which is what makes them easy to buy once and extend the following year.
What works
- Reads as a deliberate design element rather than a strand of lights
- The varied drop lengths hide small height errors in your clip line
- Cheap relative to the visual effect
What does not
- Needs a straight horizontal run — they look wrong on a raked gable
- Drops tangle with each other in storage more than any other light type
- Wind moves them, which some people find distracting
| Type | Icicle, varied drop lengths |
|---|---|
| Bulb | Mini LED, fixed |
| Colors | Warm white, cool white, multicolor |
| Use | Outdoor rated |
| Connectable | Yes on most sets |
Wreaths, garland and anything on a door
Twinkle Star Battery Operated String Lights, 16 ft / 50 LED, 2-pack
Twinkle Star
Battery sets exist for the places a cord cannot go without looking terrible — a door wreath, a mailbox, a porch column. Judged on that job they are excellent; judged as house lighting they are not.
A cord running down the front door frame ruins a wreath. That is the entire case for battery lights, and it is a good one.
This set is 16 feet with 50 warm white LEDs, sold in twos — which is the right quantity, because the places battery lights belong come in pairs: a wreath and a mailbox, two porch columns, two window boxes. If the set you buy has a built-in timer, use it; without one you are opening the door and fishing behind the greenery every evening, and nobody does that past about day four.
The thing nobody mentions in listings: alkaline batteries lose capacity in the cold, and a wreath on an exterior door is at outdoor temperature. Expect noticeably shorter runtime in a cold snap than in a mild week. Lithium AA cells hold up much better in cold and are worth the premium on anything you do not want to service in January.
Hide the battery box in the back of the wreath before you hang it, not after. This sounds obvious and it is the step everyone skips.
What works
- No cord down the door frame — the whole point
- Two sets in the pack, which is the number a door and a mailbox actually need
- Trivially movable
What does not
- Cold weather cuts alkaline battery capacity significantly
- The battery box has to be hidden, and on a wreath that is fiddly
- Replacing batteries mid-season on a door wreath is a real chore
| Length | 16 ft per set |
|---|---|
| LEDs | 50, warm white |
| Pack | 2 |
| Power | Battery (cells typically not included) |
| Use | Outdoor rated; the battery box is the weak point |

Bushes and hedges, done in ten minutes
Dazzle Bright Christmas Net Lights
Dazzle Bright
A mesh of LEDs you throw over a shrub. It is the highest ratio of visible result to time spent of anything on this site, and it is why net lights belong in most first displays.
Net lights solve one problem completely: covering a bush. Wrapping a shrub by hand takes twenty minutes and looks hand-wrapped. A net takes about ninety seconds and looks even, because it is a grid.
Dazzle Bright's sets run 360 LEDs in a mesh with eight modes. The mode controller is more useful than it sounds — on a bush the steady setting is almost always right, but the slow-fade setting reads well on a hedge line where a steady wall of light looks flat.
Where nets fail is geometry. They want a roughly rectangular volume. A tall juniper, an irregular ornamental grass, or a sparse young shrub will let the net sag into it and you get a lumpy result that reads as cheap. Measure the bush: if it is meaningfully taller than the net is wide, buy string and wrap it.
Takedown is the quiet advantage. A net comes off in one motion and folds. A wrapped shrub has to be unwrapped, in the cold, in January, and that is the job everyone underestimates.
What works
- Covers a shrub in one throw — no wrapping, no ladder
- Even spacing looks deliberate in a way hand-wrapped string never does
- Packs down flat, unlike a wrapped bush that has to be unwrapped
What does not
- Only works on roughly cube-shaped shrubs; it sags off tall or sparse ones
- A snagged mesh is harder to untangle than a string
- Fixed LEDs — no bulb replacement
| Type | Net / mesh |
|---|---|
| LED count | 360 (per the manufacturer listing) |
| Modes | 8 |
| Colors | Multicolor and warm white options |
| Use | Outdoor rated |
| Connectable | Yes on most sets |
Long eave runs in one purchase
Brightown Icicle Lights
Brightown
Brightown runs a full icicle line, which matters because buying every set of a long run from the same line is how you avoid two shades of white along one gutter.
The reason to care which brand of icicle lights you buy is color consistency. A 40-foot gutter is three or four sets. Buy them from three different brands and you will have three different warm whites in a row, which is more obvious at night than it sounds.
Brightown maintains a broad icicle line across the standard colors, so a long run can be bought as matched sets from one listing. That is the practical reason to pick it over a cheaper one-off.
Everything else is generic to the format: straight horizontal runs only, connectable end to end, and a storage problem that reels solve.
No rated-hours figure is published for this line, so we are not quoting one.
What works
- One product line covers a long run, so the whites match
- Color-changing options exist within the same line
- Widely stocked, so replacing one set mid-season is realistic
What does not
- Same raked-gable limitation as every icicle set
- Same storage tangling problem
| Type | Icicle, varied drop lengths |
|---|---|
| Colors | Full line — warm white, cool white, multicolor, color-changing |
| Use | Outdoor rated |
| Connectable | Yes |
Common questions
What kind of Christmas lights are best for outside windows?
5 mm wide-angle LED mini lights on green or brown wire, at 4-inch bulb spacing. A window is a short run viewed from close up, so a small bulb at tight spacing reads as a continuous outline while a C7 or C9 reads as a row of separate lamps. Icicle drops from the head casing are the better choice on upper-story windows.
How many feet of lights do I need for one window?
Measure the outside of the casing — head plus sill plus both jambs — and add about 10 percent for the corners. A standard 3 x 5 ft double-hung window is roughly 16 feet of perimeter, so one 24-foot mini-light strand covers it with slack to spare.
How do you hang Christmas lights around a window without drilling?
Outdoor-rated adhesive hooks on a clean, dry casing, applied in mild weather before the cold sets in. Vinyl siding hooks work for the sections set into siding. Space the hooks at roughly the same interval as the bulbs, because a hook only in each corner leaves the run sagging between supports.
Can I use battery lights on a window with no outlet?
Yes, and a window is one of the better places for them: the run is short, the battery box hides behind the casing, and most sets have a built-in timer. The limit is cold — alkaline cells lose a large share of their capacity below freezing, so budget for a mid-season battery change or fit lithium cells.
Are indoor window lights the same as outdoor ones?
No. A set mounted inside the glass lives in a warm, dry, UV-filtered space and can be a thin indoor strand. A set on the outside of the casing takes rain, freeze-thaw and direct sun and must be rated for outdoor use. If one set has to do both jobs, buy the outdoor-rated one.
