My son rides his scooter to work, school, and back and often has to come home after dark. I wanted him to have a good tactical style flashlight to keep in the storage area of his bike in case he had a problem on his travels. This 2 Pack of LETION LED Tactical Flashlight, Rechargeable Flashlights with 1500 High Lumens XML T6 IPX4 Water-Resistant 5 Modes for Clamping Fishing Bicycle (2PCS) was the perfect solutionfor him. With rechargeable 18650 batteries, an included charger, water resistant, and made of tough metal with a good grip, these lights will be durable and dependable on the off chance that he has to fix his bike or flag someone down in the dark. Plus he has an extra flashlight he can keep as a spare or to use in his room or around the house if need be. The light on these are extremely bright, even brighter than the light on some of my name brand tactical flashlights. I'm strongly tempted to order another set for myself I like them so much!
