Flexible neon light strips (also known as LED neon flex or silicone neon rope lights) are modern, highly durable alternatives to traditional glass neon tubes. Made from flexible, anti-yellowing silicone or PVC housings, these strips encase high-density LEDs to project a smooth, seamless, "dot-free" glowing illumination. They are widely used for custom DIY signage, architectural accents, bedroom setups, under-cabinet lighting, and weatherproof outdoor displays.
