Receive a Flashing Visual Indicator Whenever you Receive a Phone Call on your Landline
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.
