Review on 🚗 Water Resistant LED Parking Sensors - Car Auto Vehicle Reverse Backup Radar System, Sound Warning, Anti-Freeze Protection, 22MM Diameter Sensor, 2.3M Cable X68D (Grey) by Flavio Scarola

The reversing sensor works as expected. The red basically matches the bumper color of my 2004 F350 and looks nice. I recommend using a Unibit instead of the included cutter. Ring cutters don't cut steel as well. Use a cotton swab and some primer to sand down bare metal after the holes are drilled. Once the primer is dry, use a bit of touch up paint if you feel the need. For power, I just tapped on the reverse light wiring harness. As an extra measure to prevent the sensors from falling out of the bumper, simply apply some clear silicone to the back of the bumper (not visible) to hold the sensors in place. Note. If you're buying this for a very long car, the cable to the monitor doesn't reach the dashboard. My F350 is a crewed long bed, so about 22 feet long. I ended up installing a monitor under the back seat. The visual warning is not visible, but the audible alarm works properly. never mind I wouldn't call that a downside as the cord is long enough for most cars.
