WARNING! This product does not comply with the following lighting safety standards:


And therefor is NOT road legal in many counties (including the UK) unless used in conjunction with legal lighting but may be suitable for off road use in applications such as mountain biking.


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 places 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, 750 lumens at 13 MPH.

Charger Priority Mode
- Intelligently balances power between light and charger to optimize simultaeneous 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) 58 x (W) 42 x (H) 42 mm
- 115g (includes 36" dynamo wire)

Taillight Output
- A taillight output is available and is controlled by the headlight

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 colours.

- 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 commericially available dynamo light made in the USA.

- 3 years

What's in the Box?
- The Beacon comes with a USB-to-DC cable
- A mount is not included - there are many options available for different mounting locatons. Contact us if you need advice about mounting options.

Can I use this Light with a SON 28 Dynamo Hub?

Yes, a splendid choice.

Hello, Which mount would you recommend for mounting on the front of a Jones H bar? Thanks.
10 Dec 2018
We would probably go with - SJS Cycles part number : 23929B

Thanks - 11/12/18
What mount
11 Nov 2018
What mount do you suggest for this light to be fitted on an enigma escape bike using the drilled hole on the fork?
Most side fitting ones will work such as - SJS Cycles part number : 23928S36 or SJS Cycles part number : 12373

Thanks - 12/11/18
Can this be mounted upside down (hanging)?
27 Aug 2018
I'd like to know if I can mount this upside down (hanging from computer mount) or if waterproofness or beam pattern will be compromised.

You can mount this upside down, but the beam pattern may not be as designed, it should not affect the waterproof capability.

Hi, is a rear tailight output an extra? If not where is it on the light?
The rear light output comes fitted.

"The Beacon is compatible with most dynamo taillights, with the requirement that they do not ground to the bicycle frame.

The Beacon IS compatible with the Supernova E3 Taillight, although an extra 60Ω resistor should be wired in series between the Beacon and the E3. We have that resistor - out part #49232

Compatible taillights include:

B&M Toplight
B&M Secula
Schmidt SON
Supernova E3 (with series resistor)
The E3 does not contain a standlight capacitor. Therefore the Beacon, but not the E3 taillight, will remain on when stopped."
