We are pleased to announce a new product to our line, the Signal Tester. If you have LED-based signals that you want to test or if you have a signal with unlabeled magnet wire (e.g. BLMA) then this is the product you need! You can also use it to show off one of your signals for simple display purposes. The Signal Tester uses a 9V battery (not included) for power and is simple to use. More information about this product can be found on our website at http://www.logicrailtech.com. Click on Products then Signal Circuits then Signal Tester. You can also purchase it via our secure online store.
