Like all our INOVA flashlights, the X3A LED Bike Light offers superior light projection that increases your visibility and safety. But because it's powered by 3 AAA batteries, it also does that at a much lower cost per user hour. Its dual use design allows for easy transition between bike light and hand held device. Just slide the INOVA X3A onto the included durable Lite Ride GT and wrap the attached, flexible Gear Ties around any size handlebar-no tools required. Its bright 212 lumen beam can be set to one of three modes: High power, low power, or our innovative Safe-Day Pulse, which creates an irregular, attention-grabbing pattern to increase visibility even during the day. When you've parked your bike, the INOVA X3A is easy to remove and can be tucked into a backpack, purse, pocket, or used as a handheld flashlight to safely illuminate your path in the dark. Remove the X3A from your handlebars and prop or hang the Gear Ties for hands free lighting to assist in roadside repairs or as a signal light.
