The best selling Azur Thumb II light is one of the best value for money lights you can buy. Ideal for low-light/night conditions, the light packs a punch with an output of 1000 lumens and all while under $100! This USB-rechargeable light is very compact and lightweight. It is perfect for commuting as well as being bright enough for off-road riding and racing. It has 4 strength constant beams, intended to be used to light your path as opposed to merely making you visible to others. Helmet and handlebar mounts are included, with tool-free installation. The battery is housed in a pouch with velcro straps for easy mounting to the top tube, or can be stowed away in a saddle bag. The aluminimum body is water resistant so you'll never be caught out, and the entire unit (battery and headlamp) weighs in at just 200g.
