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 To 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.

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

Compact Design
L x W x H - 58 x 42 x 42mm
115g (includes 36" dynamo wire)

Taillight Output
A taillight output is available and is controlled by the headlight.
Taillight compatibility information can be found here.

Better colour temperature
While still in the "cool white" range, the Beacon generates slightly warmer light than other LED headlights. This results in less glare, less strain on your eyes, and does a better job reproducing natural colors.

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

Made in the USA
All Sinewave products are made in the USA. The Beacon is the only commercially available dynamo light made in the USA.
