Review on 🚗 Enhance Safety with Hopkins 28701VA nVISION Back-Up Alert and Audible Warning 3156 Bulb by Carlos Macy

I couldn't figure out how to contact the seller but I was shocked. This isn't the first of these devices that I've bought (although I don't remember if the last device was of this brand). Technically it does everything it claims to make it harder to return BUT the backup siren is so weak you have to be by the reversing light frame to hear it! My previous setup was on a Suburban with the same type of product that I bought from JC Whitney. The design looks similar (I think the previous one was based on 3056), but it's practically useless. Is this a problem with that particular block, or are they all so weak that they don't warn anyone of a backing-up truck. Who knows?
