Hazard 4 BeaconLight Kit-B w/ Boot Cover Black. Molded loops and screw backer also allow mounting to cords carabiners or ?'' webbing. Add bright 100 Lumen visibility for bike/moto jogging hiking or boating and for pro use like police military agency and industrial. One-button control cycles constant to 3 independent blinking/intensity modes. Constant mode is usable for reading maps etc. (red light good for eyes' night vision.) If mounted facing to packs/bags interiors these are a unique illumination of bag contents. Spun in the air on any cord as illustrated these create a large bright circular signal; a great option for rescue or rallying purposes. The side loops keep the light oriented to the observer without twisting away on the cord. The kit centers around the light-core (micro-USB rechargeable lithium ion battery multi-LED array circuit lens and controls) in a heat-dissipating aluminum body. The core rocks in/out of a protective rubber boot bumper which protects it and allows switching cores between mounts. So you can mount multiple boots and just move the core between them. This also gives access to the protected USB-Micro charging port (short USB-A tipped cable is included.) An upcoming optional velcro-mount molded base allows the core to be mounted on any hook and loop patch and comes with a loop adhesive portion that can be stuck to drones vehicles etc. It will also be available in BL-Kit-A which includes the core. This will be ideal for curved helmets. When mounting this unit to our shell packs such as the Pillbox Grill etc. the loop function is still retained as illustrated since carabiners cords/bungees can be passed through the boots molded loops- first around the housing so tension is directed to the solid core and pack shell via the screws not the rubber loop retaining load bearing strength. The LED core takes about 1.5 hours to charge (depending on power source) for apx. 8 hours of flash signal at max bright (at low battery mode it will only flash.) The weatherized center-logo is the power/control button and the flanking led indicators show charging/charged/low-power states. It is easy to press but the rubber raised edge prevents inadvertent presses and protects the lens as much as possible. To load pull the top loop and rock in the core from the opposite end. Unload by pushing core up through the finger opening in the boot's bottom side. Boot can host either included screws or nuts to your preference. And the Stop Gap 1 backer is used to secure this to our Hard Point grommets and to create a seal and an opposite side loop.''
