To add ultrabright flashing LED lamp,coordinated with "click" sounds!No loss in sound volume at the speaker! ULTRABRIGHT LED LAMPThis may be the brightest 5mm LEDlamp you have ever seen! It is very much brighter than standard LEDlamps of earlier years. When seenat night in darkness, the lens onthis round-top LED enables you to viewits light, even when reflected fromwhite paper at a distance of 20ft! See the photos, above. The UltrabrightLight-Emitting-Diode is mounted nearthe piezo loudspeaker. When clicks areheard on the side speaker, the LED lampdoes bright flashes!

It has not yetbeen tested on other Ludlum models. If theaudio switch is turned off, the LED lamp doesnot flash. The LED lamp connects to the piezospeaker, and there is no noticeable loss ofsound volume from the side-speaker.
