Design the Dark modifies apparel to allow lights to be added and interchangeable. Your typical light up apparel is sewn directly onto the apparel which, in time, will ware out the light and will need to be replaced by sending it back to the supplier. With our apparel, you simply replace the light by following the custom tubing system which conforms the light into your specific design. Purchasing more lights will give you the ability to match the color light to your clothing, your accessories, or even your mood. Apparel not created by us just modified with light design.
