If you’re going for unique and eye-catching, you can’t go wrong with a beautiful neon sign. While LEDs have become increasingly popular as a method of illumination, neon signs remain pieces of art. Not only are they often used as exterior and interior business signs, they are also seen as custom interior design pieces. Why not spruce up your living or dining room with a guaranteed conversation starter? With the help of chemistry, neon signs are available in a number of vibrant colours. And while the carefully created glass tubes look delicate, neon signs are surprisingly long-lasting.
