The Sylvania Stay-Lit 50-Count Color C9 Replacement Bulbs are designed to keep your holiday light strings shining all season long. Featuring Sylvania's patented Stay-Lit technology, the entire strand remains illuminated even if individual bulbs burn out, become loose, break, or go missing — eliminating the frustrating process of tracking down a single failed bulb.

These C9-size LED bulbs deliver vibrant multicolor illumination in classic holiday hues including red, green, blue, purple, and orange. Rated for both indoor and outdoor use, they withstand seasonal weather conditions while remaining cool to the touch for added safety. Energy-efficient LED construction uses significantly less power than traditional incandescent C9 bulbs, with a rated bulb life of up to 25,000 hours. Sets can be connected end-to-end (up to 30 sets) for expansive decorating across rooflines, trees, and large outdoor displays.
