Exposure's Beacon Light Diffuser Cover is just that -- a beacon. This simple add-on for Exposure Lights is perhaps the simplest, most effective accessory ever. It transforms your light from one that throws a punch of light down the trail to one that casts a strong glow in every direction. In reality, the Beacon Light Diffuser Cover makes a light like the Diablo, for example, better for general cruising down a trail. The effect is more light on the sides of the trail and under your front wheel. It also produces a more pleasant light when looking at maps or repairing a flat tire in the dark. But the aspect we like most about the Beacon is that it increases your cone of visibility to drivers and other trail users. Simply put, you'll be seen from all angles. The Exposure Beacon Light Diffuser Cover is made from opaque injection molded silicone and comes in four sizes. Size 1 fits the Joystick, Spark, Flash, Flare, Red Eye, and White Eye. Size 2 fits the Diablo. Size 3 fits the Race, Strada, and Toro. Size four fits the MaXx-D. The Beacon can be installed in seconds or removed and stashed away inside a pocket when you want a more direct beam from your Exposure light.
