Beacon Headlight FAQ

  • Integrated USB Charger Charge your phone, GPS, or any other USB device directly from the Beacon; no need for a separate charger.
  • Flexible Power Options An external, off-the-shelf USB battery pack can be connected to maintain bright, flicker-free light even when stopped or riding slowly.  Any available dynamo power replaces battery power until reaching a speed when all power is provided by the dynamo and the battery is no longer used.
  • 750 Lumens Lots of light, suitable for any style of riding. 
  • Symmetrical Beam Pattern Ideal choice for off-road riding.
  • Superior Brightness and reduced flicker at low and medium speeds. Dynamo power is optimized at low-to-medium speeds, reaching 200 lumens at just 5 MPH, 500 lumens at 8 MPH, 650 lumens at 10 MPH, and 750 lumens at 13 MPH.
  • Charger Priority Mode Intelligently balances power between light and charger to optimize simultaneous use. 
  • Standlight A supercapacitor, charged while riding, provides about 5 minutes of standlight when stopped.
  • Colours! We are able to mix-and-match different colors for the front, middle, and back of the Beacon.  Pick a combination that matches your bike or represents your country or team. Contact us about custom colors.
