Using the NiteRider Swift 300 front headlight is a breeze. First, use the built - in handlebar strap to attach it securely to your bike's handlebar. You can easily switch between the four light levels and the daylight flash mode according to your needs. When the battery is low, the fuel gauge will let you know. Simply use the USB cable to recharge it. It can be charged on the go, like when you're at home or in the office. As for maintenance, keep it clean by wiping it with a soft, dry cloth. Avoid exposing it to extreme temperatures or submerging it in water for a long time, even though it's dust and water - resistant. This will help keep your headlight in top shape and ensure it serves you well for a long time.
