Zefal Manta Deluxe 2.0 Bike Front and Rear Light Set (100 Lumens, No Tools, Multiple Modes)

These lights are exceptionally bright. The white headlight, when used at the ‘hi-beam' setting, is too bright to look at. I have flashlights that can't compare to these bicycle lights. You don't need a tool for attaching but you will need a screwdriver to remove the battery compartment cover. I like the rubber strap for attaching the clear light as it will accommodate bike frames of different thickness. These lights were attached to an electric scooter to ensure safety while riding. I won't allow the scooters to be used at night so the lights are really for neighborhood traffic to see. As bright as these lights are, vehicle drivers will see them! Great product.
