The TSL series includes Serfas' single-piece USB-rechargeable lights, designed for commuting, road biking, and off-road rides.

The TSL-200 has similar performance and design but a much smaller and lighter body than other Serfas TSL Series lights. At just 50 grams, it's the lighest high-power light Serfas offers.

Review: Light, compact light ideal for helmet spot

  • USB rechargeable.
  • Versatile mount.
  • Small size is ideal for helmet mounting (helmet mount is sold separately). I've been using this light on my helmet a lot, and its focused beam is actually an advantage here. With a wider-spread light on your handlebars, a focused light on your helmet is great for putting some extra light wherever you're looking.


  • Very focused beam - this light is good for a spotlight-type application, but isn't suitable for situations where you need off-axis lighting.
