Test 2

Digital cameras can detect infra-red light but our eyes can't. Use a digital camera, webcam or camcorder and look through the digital viewfinder at the IR LEDs, after pressing the button, the LEDs should flash.

Another way to test is to hook a phototransistor in series with a resistor and LED. The LED will flash at close range.
