The Bell® Lumina™ 500 Headlight shines with Bell's new lens design, delivering a bright, 180 lumen center beam, while the wide outer beam creates over 180 degrees of visibility. Draw the attention of drivers from the front and sides while you're braving streets and intersections. This portable headlight quickly and easily mounts to just about any handlebar with the adjustable silicone strap. When charging, the fuel gauge is handy for knowing when your light reaches full charge. Before and after your ride, it only takes the push of the power button to see exactly how much charge you have left: green is 75-100%, orange is 25-75%, and red is below 25%. Charging is fast and economical with the USB cable connection - no more buying batteries!
