This is a set of independently controlled left and right bicycle remote control tail lights and turn signals with a micro USB charging specification. *The remote control is also rechargeable. How about protecting yourself from accidents? It's so bright it'll make your eyes hurt! #BicycleTurnSignalDifferentType [Lighting Specifications] Press the left or right button on the remote control to activate the left or right turn signal (with beeping sound). Press again to cancel. Press the ○ button on the remote control to cycle through 3 modes, including hazard lights and tail light. [Installation Method] Attach the base to the handlebars and then attach the remote control! You can remove the remote control and lights to prevent theft. The tail light is separate, so you can install the left and right lights independently, or you can use the attachment to combine them into one unit. I'm not sure about the legal aspects (Road Traffic Law), but it might be possible to attach them to kickboards, etc. (if there are pipes extending up and down!) English and Chinese instruction manuals included. (Note) The original box may be folded and placed inside, so please be aware of this. *The continuous lighting time is unknown as it has not been tested. *Regarding use on rainy days, the waterproof performance is unknown, so please use it at your own discretion. *Due to being a Chinese product, there may be minor scratches on the box or the main unit that do not affect its functionality. *I am a smoker. I take every precaution, but there is a possibility that the packaging materials may have a slight odor. Please understand. Thank you for your consideration. m(_ _)m Power Source: USB Charging
