Essential Info

If you live or work in a loud environment, it's likely you have missed several calls because the sound of the ringer has been drowned out by ambient noise. The In-line Telephone Flashing Alert Light takes care of this problem so you'll be less likely to miss an important phone call in the future. The device simply installs between your existing telephone and the telephone jack, no batteries or power is required for operation. Whenever an incoming call is received, the built-in high-output LED light will flash, illuminating the area where you have it installed. The flashing will continue, letting you know that someone is trying to reach you, and will cease once your phone has been picked up or when the caller hangs up. It can be used anywhere in any phone system, video phone system, some PBX systems, and can even be used as a way to help the hearing impaired receive a phone call notification.

    The device works well and is a snap to install but could use a way to secure it in position to make the alert light permanently visible and stable. Other than that, it's terrific.
    PAUL -- dayton, OH   11/4/2012
    The light is easy to install but isn't nearly bright enough to be seen unless you're looking right at it.
    JIM -- murrieta, CA   6/7/2012
    work's great!
    JAMES -- bloomington, IL   5/21/2012

    Excellent Product
    RICHARD -- wayne, IL   12/31/2011
    does not work on phone system with multiple lines or intercom- was not indicated in product information that this would be a problem. Beware-use only if you have standard one line phone system-

    Works great as advertised. Mom can actually note the phone is ringing while watching TV!
    STRATEGIC NETWO -- washington, NC   8/11/2011
    Bought two units for 83 year old father-in-law because he could not hear the ringing of the phone; and we grew wiery of him not answering and someone having to go check on him when he would not answer.. Low and behold he has not missed a call since installing.. matter a fact it is kinda comical to see how quickly he answers his phone now; just because he can see the phone flashing... no installation required; truly plug and play; only option was where to stick on wall... If your in an apt; I would recommend to use a 3M command strip to stick; otherwise the sticky tape included WILL NOT come off. Great product!
    JAMES -- cleveland, TX   7/8/2011
    The TFAL is a simple yet effective device we purchased for an elderly church member. I was pleased with the speedy service! Thanks.
    MICHAEL -- durand, MI   5/20/2011
    works fine. Easy to install.
    DOROTHY -- delmont, PA   11/8/2010
    this little light works well--it did exactly what it was supposed to do. it is extremely easy to install on the phone line and solved a problem for our relative. it was a lot more economical than buying a flashing phone that costs over $100!!!
    GARY -- atlanta, GA   11/4/2010
    Got for father in nursing home. put it by TV. He can now see the phone ringing (Flashing) he's happy. Very easy set up, just plug it into the phone line it works. thats what the world needs things that work simple and easy as they advertise.
    JOSEPH C. -- lauderhill, FL   8/19/2010
    Works well. Good quality. I would recommend.
    SCOTT -- washington, DC   10/13/2009
    Excellent product exactly what I wanted, EXCEPT because I get phone service through my cable package, I can't plug this into just any phone jack--all the phone jacks are dormant!
