Light it up Blue! Aside from using blue in support of Autism awareness, our blue rope lights can be used to add color to parties, decorating, and holidays. Who doesn't love blue? Invest in a spool for repeated use and larger projects, or start small with a pre-cut ready-to-install rope light kit. Our concave interior bulb tip radiates light 120 degrees, versus the one-directional light of a round LED. LED rope light saves on energy, always remains cool to the touch, and lasts longer!
