This is a front and rear light set by Powlaken. They have super bright LED lights and are rechargeable using USB. The headlight takes 2 hours to fully charge and then will last 3-10 hours depending on the mode. The light has a sensor mode where it will change the brightness according to the conditions or you can have a high light, energy saving or SOS flashing mode. The back light has a bright, low or flicker light option. There is even a battery indicator so you will know when to charge it. They are both really easy to install with no tools needed.
