Review: Easy to install and just about the only way to go without splicing into wires - Installed on a 2014 Chevy Volt. Because it's in a pretty thick plastic housing, the beep isn't very loud but on the positive side, that means less chance the neighbors will complain or pedestrians getting startled compared to the OSHA approved beepers. I think it's loud enough for someone who's near the car to hear but it definitely isn't a substitute for a visual check (fortunately the car also has a backup camera). I didn't want to splice into the wiring so this is pretty much the only other option available. Hopkins says there's a lifetime warranty so I'll keep my fingers crossed with the halogen bulb and beeper. Review: Not loud Back Up Warning - Not loud enough,can not hear more than 10 to 12 feet from alarm. I have had other brands that I could 100 or more feet away. I purchased another one that I had to wire in to the reverse light wire. Now it works really good. I left the other one in, being I needed a new bulb anyway. ## Features - Warns pedestrians with an audible "beep-beep" when vehicle is placed in reverse - Simply replace existing back-up bulb - No wiring necessary - Made from high quality material and includes patented technology - Fits vehicles that use a #3156 style light bulb - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00009W3SR | | Auto Part Position | Right | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #1,215,472 in Automotive ( See Top 100 in Automotive ) #574 in Backup Monitors & Alarms | | Brand Name | Hopkins Manufacturing | | Color | Red | | Customer Reviews | 3.4 3.4 out of 5 stars (100) | | Fit Type | Universal Fit | | Global Trade Identification Number | 00088797201015 | | Included Components | 50 Watt Halogen Super-Bright Back-Up Alert™ Bulb | | Item Type Name | Hopkins 20101VA Back Up Alert® 3156 12 Volt (Retail Box) | | Item Weight | 0.1 Pounds | | Manufacturer | Hopkins Manufacturing | | Manufacturer Part Number | 20101VA-CL-EN | | Manufacturer Warranty Description | 1 year manufacturer | | Model Number | 20101VA-CL-EN | | Package Quantity | 1 | | UPC | 088797201015 | | Unit Count | 1.0 Count | ## Product Details - **Auto Part Position:** Right - **Brand:** Hopkins Manufacturing - **Color:** Red - **Fit Type:** Universal Fit - **Item Package Quantity:** 1 ## Images ![nVision Hopkins 20101VA-CL-EN Back-Up Alert with Audible Back-Up Warning 3156 Style Light Bulb - Image 1](https://m.media-amazon.com/images/I/A16uY+EA-mL.jpg) ![nVision Hopkins 20101VA-CL-EN Back-Up Alert with Audible Back-Up Warning 3156 Style Light Bulb - Image 2](https://m.media-amazon.com/images/I/51h5ER1N3dL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install and just about the only way to go without splicing into wires *by R***W on October 24, 2017* Installed on a 2014 Chevy Volt.
