This Costco 2-pack includes two Sylvania StayLit 100-count mini LED light strings in pure white, sold as a set (Costco item 1487016). Each string features 100 super-bright, long-lasting LED bulbs designed with Stay-Lit and flicker-free technology, so the remaining lights stay on even if one bulb goes out.

The strings are rated for both indoor and outdoor use and can be connected end-to-end with up to 22 sets, making them ideal for decorating Christmas trees, mantels, stairways, or exterior landscaping. The LED bulbs consume significantly less energy than traditional incandescent mini lights and have a longer operational lifespan.
