This Adnkwolivt Happy Birthday Neon Sign is a 16.5 x 12 inch USB-powered warm white LED backdrop light designed to add reusable, dimmable glow to birthday parties and home décor.

Compact and durable, this neon-style LED sign uses flexible silicone tubing fixed to an acrylic backboard to recreate the look of classic neon without fragile glass. It includes a 180 cm USB cord, a 45 cm metal hanging chain, and an inline dimmer that remembers the last brightness setting. Lightweight and easy to mount or prop, the sign is built for repeat use at parties, photo backdrops, bedroom accents, and event displays.

How bright is the sign and can I adjust it for different moods?

The neon uses an LED strip inside soft silicone tubing and features an integrated dimmer with 10%–100% brightness control. You can toggle power with the main button and fine-tune light level with up/down controls; when turned off and on again it returns to the previous brightness setting.

• 10%–100% adjustable brightness for soft night light to bold backdrop glow
• Memory function restores last used brightness after power cycles
• Warm white color reduces glare while providing clear, flattering illumination
• Inline controller is easy to reach and operate during setup or events

Is this neon sign durable and safe for repeated use?

Yes — the sign replaces fragile glass with silicone LED tubes mounted on an acrylic panel, making it lighter, more impact-resistant, and cooler to the touch. The LED technology uses low voltage and produces minimal heat, so it’s safer around children and party crowds.

• Silicone tubes and acrylic backboard instead of glass for durability
• Low-voltage LED operation with no hot surfaces
• Bright, stable color output without flicker or rapid dimming
