Rearview and side mirrors are handy but even the scope they offer is limited. And as convenient as eyes in the back of your head would be, sometimes all that’s needed is a high-quality back-up alarm to alert others that you’ve put it in reverse. That way, you won’t have to worry about having your head on a swivel.

AutoAnything carries a wide selection of back-up alarms from industry leaders, one of which even rings out in plain, attention-grabbing English, “Attention, please! This vehicle is backing up!” And this aftermarket alarm, as with the others, won’t stop repeating this warning until you shift into drive. We back every potentially life-saving addition to your 12V vehicle’s arsenal with a 1-Year, Lower Price Guarantee.
