Sporting Goods, Fitness and Recreation Equipment Design Mix mudguard Multifunction mudguard by HAPPY BUDDHA DESIGN STUDIO The Integration of Rear Light and the Mix Mudguard. The rear light is a warning device and stays on the bicycle by itself most of the time. However, when the weather condition is poor, you can simply and quickly install the Mix Mudguard. The warning light can be projected to the Mix Mudguard; the translucent Mix Mudguard can be penetrated by light to form a larger warning area. This increases the safety by providing a better warning signal when riding in poor weather.
