Using these lights is a breeze. For the Day Blazer 1500 front light, you can easily mount it on your bike's handlebar or your helmet with the included action-camera style mount. Just charge it via USB for 5 hours using the lithium-ion battery. Make sure to turn on the BLITZ Daytime Running Mode during the day to be highly visible. For the Dayblazer 65 rear light, simply use the included charging cable to recharge it in 2 hours with the lithium polymer battery. You can see the charge status from the LED fuel gauge.
When using, keep in mind that these lights are IP67 waterproof, so they can handle some splashes and light rain, but don't submerge them for long periods. For maintenance, regularly check the mounts to ensure they're secure. If the lights get dirty, gently wipe them with a soft, damp cloth. Store them in a dry place when not in use to prolong their lifespan.
