Please select options Unavailable


The new Beacon is hands down the best dynamo headlight in production, and it's made in the USA.

750 lumens

Starts charging at around 5 mph (700c wheels), an industry best

Symmetrical beam pattern

Ideal choice for off-road riding.

Superior brightness at low and medium speeds


Includes an integrated USB Charger to charge your phone, GPS, or any other USB device directly from the Beacon; no need for a separate charger. For bike touring and bikepacking, you can also charge an external battery pack for an extra store of power.

750 Lumens

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.

Simultaneous power distribution: the charger works even while your lights are on. Intelligently balances power between light and charger to optimize simultaneous use.

Standlight: A supercapacitor provides about 5 minutes of standing light when stopped.

Color options:
anodized black
anodized silver
polished silver

Mix and match colors: By special order, you can choose 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 to place your order.

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:

Power to the tail light is controlled by the front light

Better color 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.

Weatherproof (see the photo where the light is submerged in water).

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.

3-year Warranty

What's in the box?

The Beacon comes with a USB-to-DC cable.
