When cycling at night, it's important not just to be seen from the front and back but also from the sides. In order to make that happen, bicycle lighting systems typically either add dedicated side lights or they divert part of the main headlight beam. The Ding headlight, however, puts out one beam that shines forward, along with a second one that lights up the road directly to either side of the bike.

The Ding's forward beam uses two LEDs for a maximum output of 400 lumens, ensuring that riders can see the road ahead. A separate LED on the underside of the light puts out another 150 lumens, creating a 3 x 1.5-meter (9.8 x 4.9-ft) rectangular bar of light on the asphalt beneath.

Both beams can be switched to lower output modes for longer battery life. At the maximum setting, the USB-rechargeable 3.7-volt 2,500-mAh lithium battery should be good for a claimed 2.5 hours of use. Users are alerted to low charge levels via integrated colored LED indicators.

The Ding is attached to the underside of the handlebars via a swiveling silicone strap. To remove the light for charging (or to keep it away from thieving hands), users can quickly detach it from a built-in "holster" instead of taking the strap off every time.

The light's Australia-based designers are currently raising production funds, on Kickstarter. A pledge of AUD$95 (about US$73) will currently get you one, when and if they're ready to go. The planned retail price is AUD$120 (about US$92).

It is now 20 or maybe even 25 years since bicycle lights front and rear are mandatory to be visible from the side by law around here. This is accomplished by emitting a defined quantity of light sideways, so that a street legal bike emits light 360°. It is a great achivement that this has now been discovered elswhere.

The light road itself being lit up is not likely to be visible when it matters most, e.g. when there are other cars in the field of vision of the driver who needs to be alerted. Car headlights simply overpower any incident light on the road. It is why such systems, until now only front and back, have never sold well. However, light which travels directly from the light unit to the driver who needs to be alerted does stand a chance of being noticed. Making such direct light visible over a wide angle is a solution, relying on the incident light on the road being visible from a wide angle is not.
