Tail gate alert

Awesome tailgate alert system! I am so happy to finally own this system and I have no regrets with my decision to purchase it. I was instantly attracted to this item because, it is not uncommon for me to back into things. With this alert system, it will give off a red beam in the driver side mirror to let you know something has occurred. I appreciate the fact that there are only 3 components to the installation, which made it very simple to install. The system is ran off of 2 AA batteries, which also alerts with a yellow beam of light when they are needing to be changed. I highly recommend this item, because it is truly beneficial.  "I received this product at little to no cost in exchange for my unbiased and honest feedback.
