Beacon 2 Instructions


  1. Mount the Beacon to the bicycle using standard mounting brackets.  The Beacon uses a standard 10mm mounting tab and is compatible with mounting hardware from Schmidt, B&M, Supernova, etc.  Many options are available from Peter White Cycles, among other bike shops: 
  2. Connect the long cable from the bottom of the Beacon to the dynamo.  The wires can be connected in either polarity. More information about connecting to the dynamo is available here: 
    Dynamo Hub FAQ
  3. The short cable from the bottom can be connected to a taillight.  See this page for more information about compatibility with various dynamo taillights:
    Beacon Taillight Compatibility
  4. The Beacon taillight output is DC.  The "striped" taillight wire is the positive lead.  This should only matter when connecting to a DC taillight like the Supernova E3 or Exposure RedEye.  For most taillights (B&M, Schmidt, etc) you can connect in either polarity.
  5. Be careful to prevent the taillight wires from shorting together or shorting to the bicycle frame.  Heat shrink tubing or electrical tape can be useful for this.  If not using a taillight the exposed ends of the taillight wires should be clipped off.
  6. If using a USB battery pack to power the Beacon, use the USB-to-DC cable to connect the battery to the barrel connector on the back of the Beacon.


  1. Setting the toggle switch in the middle position turns the light off.  The USB charger is enabled in this mode.  As no power is used by the light, the best USB charger performance is available in this mode.
  2. Setting the toggle switch in the up position enables high brightness for the light.  The USB charger is disabled in this mode.
  3. Setting the toggle switch in the down position enables low brightness mode.  The USB charger is enabled in this mode.  The brightness of the light is steady whether the USB charger is used or not.
  4. When using external battery power the light alternates between steady and blinking mode each time the toggle is moved into the down position.
