Introducing the Sinewave Beacon dynamo headlight!

Beacon Headlight FAQ

Features:

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.

Standlight

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.
