This holiday, make your house merry and bright with a string of warm incandescent mini Christmas lights. The 100 clear bulbs are spaced a mere 2 inches apart on green wire making them the ideal lights to wrap wreaths, mantle pieces, and topiaries. UL listed for indoor/outdoor use, the 18 foot string averages 3,000 hours of trouble-free lighting. Up to 3 sets can safely be connected end-to-end. Let your house glow with these durable and festive lights.
