Using the Lezyne Micro Drive Pro 800XL front light is easy. First, use the versatile mounting strap to attach it securely to your handlebar. You can switch between the eight output modes according to your needs. For example, use the Daytime Flash mode when riding during the day to be more noticeable. When you need a long - lasting light, choose a lower - lumen mode. To charge the light, it takes about 4 hours. Make sure to keep the charging port clean and dry. When not in use, store the light in a cool, dry place. Avoid exposing it to extreme temperatures or moisture. If the light gets dirty, you can use a soft, damp cloth to gently clean the body. That's all you need to know to keep your light working great for a long time.
