As the first November snowflakes fall across North America, a special "annual competition" has quietly heated up from Boston on the East Coast to Los Angeles on the West Coast of the United States—the 2025 US Christmas House Decoration Competition is sparking a decoration boom on a community-by-community basis. Known as the "light PK", this nationwide event has long transcended its essence of "competing for beauty" and become a cultural symbol carrying American community spirit, family warmth, and holiday traditions. This article will detail the core rules of the 2025 key competitions, dissect the core of PK culture, and present award-winning decoration tips, providing a one-stop reference for participating families.

The US Christmas House Decoration Competition is characterized by "localized hosting" with no unified national rules. Events organized by local city governments, chambers of commerce, or community organizations all bear regional marks. The 2025 competition rules of the following three benchmark cities are key references for participating families and also hide "winning signals".
Ashland’s Residential Christmas Decorating Contest in Wisconsin is a classic event in the Midwest. In 2025, it continues its "community-friendly" nature, with core information directly addressing the needs of participating families:
-
Key Registration Details: Open only to Ashland residents. Applications must be submitted by email (ashlandchristmas@163.com) or in person by 16:00 on November 25 with no entry fee, and the house address and decoration theme must be indicated.
-
Judging Criteria: The jury (composed of designers and community representatives) will conduct on-site reviews by car from December 8 to 10 at night, focusing on four core dimensions: "Christmas theme relevance", "creative use of lighting", "decoration balance", and "community adaptability", rejecting "excessive luxury".
-
Award Highlights: The champion receives $1,000 in "Chamber Dollars", the runner-up $500, and the third-place winner $250, which can be directly used at more than 230 cooperating merchants across the city (including restaurants, home furnishing stores, and hardware stores), realizing "winning equals subsidizing daily life".
-
Hidden Requirement: Decorations must remain in place until January 1, 2026, to ensure the holiday atmosphere lasts, which is also an implicit scoring item for "community contribution".
Eureka’s 6th Annual Mayor’s Holiday House Decoration Competition in California took "public participation" to the extreme in 2025, becoming the most popular event on the West Coast:
-
Participation Scope: Open to all Eureka residents (including apartment tenants, who can participate with balcony decorations). Registration is available by filling out a form on the city government’s official website by December 2, and uploading a decoration sketch can earn "creativity bonus points".
-
Judging Innovation: 50% of the score comes from professional judges, and 50% from public voting (the official website voting channel is open from December 15 to 25). The "People's Choice Award" is independent of the main awards, and winners will be invited to participate in the municipal Christmas parade.
-
Featured Event: A "Christmas Light Shuttle Bus" will operate from December 20 to 22, offering free rides for citizens and tourists to visit participating houses. The bus is equipped with commentators who explain the creative stories behind each house’s decorations, and high-popularity houses will be marked as "must-see stops".
The joint event held by Richmond Hill in Georgia and South Bryan County attracted families of all styles in 2025 with "full-style inclusiveness", and its subdivided awards can be called a "creativity carnival":
-
Core Awards: 8 major awards are set up, including "Most Original", "Best Lighting Gradient", "Best Inflatable Decoration", "Griswold Award" (paying tribute to the exaggerated style in National Lampoon's Christmas Vacation), and "AI Creativity Award" (bonus points for using intelligent lighting design tools), covering all styles such as minimalism, retro, and childlike fun.
-
Timeline: Registration is open from December 1 to 6; the list of participating houses and "check-in map" will be announced on December 10; judging will start after December 15, and results will be announced via Facebook and local newspapers.
This century-old "decoration competition" has become a winter tradition in the United States, with its core lying in the cultural value it carries—it is not an isolated "family show", but an important carrier connecting neighbors, inheriting memories, and activating the community, which is also the soul of PK culture.
The layout of detached houses in American suburbs often leads to sparse daily interactions between neighbors, but the Christmas decoration competition has become a natural "social bridge". According to 2024 event data from Ashland, 78% of participating families reported "knowing more than 3 neighbors through the competition": some borrowed lighting installation tools from neighbors, some teamed up to group-purchase decoration materials, and even families on entire streets agreed on a "fairy tale town" theme to jointly create a coherent decoration scene.
Eureka’s "shuttle bus tour" has further amplified this connection: passengers include local elderly sharing past decoration stories and new immigrants consulting participation tips, and the distance between strangers has quietly melted away in the relaxed topic of "commenting on lights". "Last year I helped the elderly neighbor next door hang Christmas lights, and now we walk our dogs together every week." Diane’s experience in Eureka is a vivid embodiment of the "connection value" of PK culture.
The core logic of American Christmas decoration is "emotional bearing" rather than "price competition". The decorations of many participating families include "old items" passed down from generation to generation: the Martin couple in Ashland paired a handcrafted wooden sled made by their grandfather in 1980 with modern RGBIC light strings; the winning family in Richmond Hill hung their children’s hand-drawn Christmas cards on light strings, mixing them with antique glass Christmas balls.
These "fusion of old and new" decorations are often more able to move judges. As a judge of the Ashland event put it: "We don’t care how expensive the decorations are, but whether they hide 'family stories'—those scratched glass balls and crooked hand-drawn cards are warmer than pure gold decorations." This "memory inheritance" has made PK culture transcend the "competition" itself and become part of family traditions.
The Christmas decoration competition is also a "small engine" for activating the local economy in winter. Ashland’s "Chamber Dollars" reward directly binds the event to local consumption. During the 2024 event, sales of Christmas decorations at local home furnishing stores increased by 42% month-on-month, and restaurant customer flow rose by 25%; handcraft workshops in Richmond Hill launched "Christmas Decoration DIY Courses", specially designing tutorials for making pinecone wreaths and wooden snowmen for participating families, with course bookings fully occupied one month in advance.
From decoration material procurement to tourist "light-viewing consumption", the event has formed a virtuous cycle of "participation - consumption - community benefit", which is also an important reason why local governments actively organize the event—a decoration PK not only warms people’s hearts but also boosts the economy.
Combined with 2025 smart lighting trends (such as RGB, design tools) and judge preferences, to stand out in the PK, it is necessary to focus on the three cores of "intelligence, durability, and warmth". The following tips have been verified by past award-winning cases and can be directly reused.
The favored decoration technology in 2025 is smart control,achieving dynamic effects such as "snowflake flow" and "red-green gradient".
Practical Tips: Set roof lights to "three-color zoning"—red for eaves, green for roof ridges, and warm white for wall corners to form a layered gradient effect; connect to Alexa or Google Home to set smart scenes such as "auto-on at sunset" and "switch to low brightness at 22:00", which is both worry-free and technologically advanced.
Permanent outdoor lights with the feature of "install once, reuse for years" have become a "bonus item" in the 2025 event. Such products need to meet IP67 or higher waterproof rating (resistant to heavy snow and rain) and support cutting and expansion (to fit different roof sizes). The champion family of Ashland in 2024 won the award precisely by virtue of the "three-color gradient + low power consumption" advantages of permanent lights.
Purchasing Points: Prioritize models that support "cross-holiday modes"—use red-green color scheme for Christmas and gold-red gradient for New Year; judges value decorations with "high practical value" more.
High-memorability decorations often carry "community-specific marks". For example, participating families in Richmond Hill made mini light models of iconic sculptures in local parks; residents in Eureka spelled out "Welcome New Neighbors" with light strings, paired with an inflatable Santa Claus waving, which not only fits the Christmas theme but also conveys community warmth.
Low-Cost Creativity: Collect Christmas wish cards from community children, encapsulate them in transparent acrylic boards and hang them on light strings; place a small table with "free hot cocoa" in the courtyard, paired with warm light strings, turning decorations from "visual viewing" into "interactive experience" to easily gain the favor of judges and the public.

-
Q1: Should I choose IP65 or IP67 for outdoor Christmas lights?
A1: Prioritize IP67 (submersible) in snowy northern regions, and IP65+ is sufficient in rainy southern regions. Events such as Ashland and Richmond Hill clearly state that "failure to meet waterproof standards will result in disqualification", so check product certifications when purchasing.
-
Q2: Must smart lights be connected to an APP?
A2: Not necessary, but products supporting voice control or timing functions are more likely to earn "creativity points". For elderly participants, choose simplified models with "one-click switch to Christmas mode".
-
Q3: Can I participate if I rent a house?
A3: Most events allow it. Eureka and Richmond Hill explicitly state that "balcony and windowsill decorations are eligible for participation". It is recommended to choose adhesive lamp holders without drilling to avoid damaging walls.
The arena of the 2025 US Christmas House Decoration Competition has never been a "luxury arena", but a "warm expression platform". From Ashland’s Chamber Dollars to Eureka’s shuttle bus tours, from the dynamic light and shadow of RGBIC light strings to the hand-me-down wooden sled, the ultimate winner of this PK will always be families who can convey warmth and connect the community through lights.
This Christmas, there is no need to pursue extremely expensive decorations. As long as you integrate family memories, echo community warmth, and match with intelligent and durable lighting technology, your house will become the most eye-catching scenery on the street. Wish all participating families double happiness of honor and neighborhood warmth in the 2025 light PK!
