This decorative LED string light features a series of 8 mm diamond‑shaped bulbs, each capable of displaying vibrant red, green, and blue (RG / RB) tones—or transitioning smoothly among them—creating a captivating multicolored display. Encased in durable clear plastic lenses and strung along a sturdy insulated wire, the lights are often arranged in “serial” form—meaning they blink or chase in coordinated patterns, adding dynamic motion to your décor. Ideal for indoor or outdoor use, these lights are typically designed to be weather‑resistant and low voltage—commonly powered at around 12 V—making them both safe and energy‑efficient. Their compact 8 mm size delivers a bright yet delicate sparkle, perfectly suited for hanging around doorways, windows, trees, or event spaces. With options often including 60–100 bulbs per strand and offering multiple blinking or steady‑on modes, they’re great for festivals, weddings, parties, or year‑round ambient lighting.
