Transform your house into a winter wonderland with this set of 50 jumbo colour-changing lights. With approximately 12.3 metres of green cable, these lights will look fantastic on porchways, gable ends, rooflines or around a window. Suitable for indoor and outdoor use, although the transformer should remain indoors at all times. Although these bulbs are non- replaceable, they are highly energy efficient and have a lifespan far greater than that of ordinary filament bulbs. Warning: Keep away from direct heat or flame.
