ComboJoy Purple Happy Birthday Yard Sign Kit — 18-piece, 16" Letters with 49.2 ft LED Lights, Waterproof & Reusable

ComboJoy's 18-piece purple Happy Birthday yard sign kit is a complete weatherproof lawn display with 16" letters, a personalized age plaque, 49.2 ft of LED string lights, and 36 stakes to stage an eye-catching outdoor or indoor birthday setup.

Ready-to-install and reusable, this kit combines lightweight, UV-resistant 4mm polypropylene signs with battery-operated LEDs and double-sided tape—so you can decorate a front yard, garden, driveway, or party room in minutes. The pieces are designed to withstand rain and sun while offering customization with two of each number 0–9, a personalized sign, and small decorative accents to match.

How easy is it to set up the yard sign and lights?

Assembly is straightforward and tool-free: slide letters and decorative signs onto the included stakes, position them in the lawn, then string LED lights where you want added glow. The roll of double-sided tape secures lighter pieces or moves the display indoors if the weather changes.

• Insert pre-cut letters into stakes—no drilling required
• Three 16.4 ft LED strings (total 49.2 ft) run on batteries for flexible placement
• Double-sided tape keeps lights or small signs mounted on walls or doors
• 36 stakes provide stable support across uneven ground

Can I personalize the sign for any age and reuse it?

Yes. The kit contains two sets of digits 0–9 so you can form any age from single to triple digits and swap numbers between events. The durable polypropylene construction and UV fade resistance mean the signs hold color and shape season after season.

• Two of each number 0–9 for flexible age combinations
• Large 16" personalized plaque for the milestone number or message
• 4mm thick material resists bending and moisture
• Easy to store and reuse for future birthdays

How does the kit perform outdoors and in varied weather?

Designed for outdoor use, the signs are water-resistant and made from thick polypropylene that tolerates rain and sunlight. If severe weather approaches, the lightweight pieces can be moved indoors and secured with the included non-marking tape without damaging surfaces.

• 4mm polypropylene for water and wind resistance
• UV-resistant inks help prevent fading from sunlight
• Non-marking double-sided tape for temporary indoor mounting
• Battery-powered LEDs avoid outlet dependence in yards

What visual effect do the LED lights and decorations create?

The 49.2-foot total LED length wraps around letters and stakes or weaves through shrubbery to add color and nighttime visibility. Paired with the purple lettering and decorative accents, the lights create a festive, high-impact focal point for photos and curbside celebrations.

• Three strings of warm LED lights for even illumination
• Purple theme enhances photogenic, celebratory look
• Decorative mini signs fill gaps and add detail
• Works equally well for daytime curb appeal and evening glow
