Using this lighting set is easy. First, take out the set from the package. You'll find the Beamer 1 headlight and the Blinky 3 taillight, along with the included batteries. Install the batteries in both the headlight and the taillight according to the polarity markings inside. Attach the headlight to the front of your bike and the taillight to the rear. When you're ready to use them, simply turn on the switch. For best results, keep the lights clean. Wipe them with a soft, dry cloth regularly. Avoid exposing the lights to water for long periods as they are not rechargeable and water might damage the batteries. Also, replace the batteries when the light starts to dim. This will ensure you always have a well - lit ride.
