Be sure to use the pack fixed, rather than free hanging, and the cable is not stretched tight.<br><br> Warm Tips: <br>Sometime you would hear a slight buzzing noise from the battery pack when powered on. It is normal phenomenon. EL wire glow needs a high frequency pulsed power source which frequency falls squarely at the frequencies that are more sensitive to hearing. But it is a weak sound and is easy for most people to accept, especially when you hide the pack at your waist or in the pocket.<br><br>Packing include: <br>1 x EL Wire Glasses <br>1 x Battery Pack (battery not included)
