ComboJoy Happy Birthday Yard Sign Kit — 16 pcs LED Letters, Personalized Age & Weatherproof

ComboJoy 16 Pcs Happy Birthday yard sign kit is a customizable, weatherproof outdoor and indoor decoration set with LED-lit letters, 20 number stickers, stakes and bonus balloons to display any age.

Whether you’re planning a front-yard surprise, a driveway parade, or a cozy indoor gathering, this full kit gives you everything to make the birthday message pop. The set pairs rigid, corrugated plastic letters with battery-powered LED lights and reusable number stickers so you can spell “HAPPY BIRTHDAY” in vivid colors and show any age. Durable materials, multiple mounting options and included extras mean easy setup, brighter photos, and decorations you can use again.

How do I personalize the age on these yard signs?

Personalizing the age is quick and tool-free. The kit includes 20 number stickers—two of each digit from 0–9—so you can combine digits to create any two-digit age. Apply the sticker to the front of the sign where you want the number to appear and press to secure.

• Includes 20 adhesive number stickers (two of each digit 0–9).
• Works for single- and two-digit ages (e.g., 1, 21, 65).
• Stickers remove cleanly for reuse on other signs.
• High-contrast digits remain readable at a distance.

What weather resistance and durability features does the kit offer?

The signs are made from corrugated plastic designed to tolerate rain, wind and usual outdoor exposure while remaining lightweight. The printed faces resist fading and the rigid board stays flat so the letters keep their shape through multiple parties. If severe weather is expected, the set includes easy indoor mounting options to protect the display.

• Corrugated plastic construction for water resistance and rigidity.
• Weatherproof printing that maintains bright colors outside.
• Non-marking double-sided tape for indoor repositioning.
• Reusable for future birthdays to reduce waste.

How do the LED lights and stakes work for outdoor displays?

Each letter has built-in LED lighting (batteries not included) that brightens the display for evening events and photos. The package includes 32 stakes that insert into the bottom of the letters, anchoring the assembly into grass or soil for stable placement. Stakes give you flexibility in spacing, height and layout across a lawn or garden.

• Battery-powered LEDs add color and visibility after dark.
• 32 sturdy stakes for secure ground installation.
• Adjustable spacing lets you create straight or curved displays.
• Lightweight letters stay stable when staked into soil.

What extras come in the box to complete the look?

ComboJoy includes a few extras so you don’t need multiple purchases to finish the scene. Alongside the 16-piece letter set and stakes, you’ll find 20 coordinated balloons and the adhesive tape for indoor use. These additions give you a cohesive color palette and more styling options straight out of the box.

• 20 color-coordinated balloons for additional decoration.
• Non-marking double-sided tape for sticking letters to walls.
• Clear instructions for quick assembly and layout tips.
