If you like to wear your sunglasses at night, then a pair of novelty wholesale flashing sunglasses might be the perfect accessory for you. Or, it may be a perfect addition to a Halloween costume or for a themed party. Most pairs of flashing sunglasses use LEDs powered by small 3V batteries (similar to a watch or hearing aid battery). The companies who sell the sunglasses usually sell the appropriate batteries as well.
These shades vary in size, shape, color, and even blinking pattern. Because these sunglasses are considered novelty items, many companies only sell them in bulk. However, they only cost around $5 (and often less) per pair. However, some companies do allow purchasers to get one pair at a time and offer special discounts if you buy a certain number of pairs. Many companies who make flashing sunglasses either specialize in novelty items in general, or more specifically in flashing novelty items. Thus, once you find a pair of flashing sunglasses that you like, chances are you will be able to find plenty of other novelty items for your enjoyment through the same wholesale company.
