This ingenious parking sensor can give even old cars and trucks new rear camera technology

As of May 2018, it's federal law that all new cars and trucks in the U.S. must be equipped with  rearview monitoring technology. However, that still leaves millions and millions of vehicles produced before two years ago without rear-mounted sensors capable of telling you when you're about to back into a BMW while parking, for instance.

For decades, parallel parking has been a fear of all new drivers and an ongoing concern even for seasoned wheelmen and women. That's because all it takes is a moment of lost concentration to inch to close to another vehicle and cause damage to your car and theirs.

With the Light Smart Solar Powered Parking Sensor by FenSens, drivers can put those worries to bed, offering a simple, effective method avoiding parking problems.

The ultrasonic, hyper-attenuated sensor mounts easily to the front or back of your car or truck with no wiring needed. Once it's synced to the FenSens app on your phone, it serves as your early warning system, issuing both audio and visual alerts to your phone if your car is getting too close to anything. In fact, the G Sensor technology will also tell you exactly how close you are, so you can also make sure you aren't too close or too far, but just right.

After its initial powerup, this sensor is 100 percent solar powered, so you'll never have to worry about it running out of juice. It's also completely weatherproof.

And if you happen to roll using either Siri or Google Voice commands, the FenSens app is completely compliant.

With the FenSens sensor, everything from older model vehicles back to legitimate classics can enjoy the advantages of new school technology without a massive and costly electrical overhaul.

The Light Smart Solar Powered Parking Sensor by FenSens is usually priced at $129, but with the current offer, you can put a parking sensor on any vehicle for under $100, just $89.

Prices are subject to change.
