Introducing the Sinewave Beacon dynamo headlight!

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 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.


                      • A supercapacitor, charged while riding, provides about 5 minutes of standlight when stopped.

                        Color Options

                          • 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.

                          Mounting Options

                          • The 10mm mounting tab is compatible with mounting hardware from B&M, Supernova, Schmidt, etc.

                          Compact Design

                          Taillight Output

                            • A taillight output is available and is controlled by the headlight.


                              • Designed to be used in any conditions.  Multiple seals protect against water ingress, electronics are potted in epoxy, and all connectors are designed for resistance to the elements.
