Easy to install. Drill, screw driver and small wire crimp. Attached to inside of truck bed by tail lights. Drilled small hole inside truck bed wall. Ran a short piece of wire to tail light reverse light. Ground attaches to where back up alarm is attached. Works great!

1.0 out of 5 stars Didn't last, and no warranty
Reviewed in the United States on May 5, 2013
Style: Commercial Grade Back-Up AlarmVerified Purchase
I bought this because I wanted the safety advantage of others knowing I was backing up. It worked great, for about 2 months. One day it just stopped working. It wasn't raining or snowing that day, besides I had this under my rear bumper to protect it from the weather. I gave them the benefit of the doubt and thought maybe my wiring was the problem. Nope. When this went out I ordered an Ecco smart alarm. I hooked that up and it works as designed. I even took this BA-107 and connected it directly to my battery and there was no sound. So much for it being heavy duty.
I pulled my instruction sheet and there is no mention of a warranty. I couldn't find one on their website either. I did a Google search and was only picking up warranty information on their horns. Those warranties are for only 90 days, and you have to pay shipping both ways! At that rate it is cheaper just to buy another alarm. As long as you don't buy one from Wolo.

5.0 out of 5 stars Is that UPS?
Reviewed in the United States on March 21, 2010
Style: Back-Up AlarmVerified Purchase
Great back-up alarm. I put mine on a switch so that I'm not annoying my neighbors when I'm not in an area that requires the use of the alarm, but when it is on, it is nice and loud. This is a light-weight easy-to-install warning alarm that has stood up to the elements well so far. I have it mounted under the rear bumper of my truck and it has seen rain, ice and snow with no complaints. Want to sound like a UPS truck (or otherwise just ensure that people are aware that you are backing up)? This alarm won't disappoint.

4.0 out of 5 stars Very Loud.
Reviewed in the United States on February 19, 2014
Style: Back-Up AlarmVerified Purchase
The unit looks solid and well built. I back out of blind driveway and I am always amazed at number people who walk behind a car moving in reverse when they know (or should know) that they can't be seen. My only complaint is the unit is a little too loud for use in a residential area. This would be a really great unit if it had a volume control. Much better suited for a construction site than a neighborhood. I will see if the neighbors complain. What am I thinking? They will either complain or hold a grudge. I probably should muffle it a little.

4.0 out of 5 stars Backup alarm
Reviewed in the United States on May 29, 2014
Style: Back-Up AlarmVerified Purchase
This was easy to install - attach under the back of car and run a wire to backup light.

Here in an AZ over 55 community it is supposed to warn people NOT to walk or drive their golf cart behind the car when it sounds, as I am backing up.

Mixed reaction - some are aware car is backing up - some think it is the signal to position themselves right behind the car others see it as the warning to see if they can pass by before the car gets out of space.

Overall - I would get another, it is a good idea.
