The Combo SmartCord is a unique power cord with a power-on indicator, an alert lamp that warns you of radar and laser, and a convenient mute button right on the lighter plug! This is a half straight, half coiled cord for a cleaner look and a longer reach. It is the perfect addition for any vehicle, especially when reaching the mute button on the windshield mounted radar detector is a stretch. Also, for discreet night driving, put your Beltronics or Escort detector in dark mode and use the SmartCord for visual alerts. Other drivers won't know you have a detector.
