Abstract: A pen with both music and motion lighting function but capable of emitting multiple color light source variably accompanying the cadence or rhythm of pleasant played music for fascination, enjoyment and amusement of individual's sight and hearing. A music-light generating means disclosed is fitted into a tubular cylindrical holder invented as a sound box to have sounds generated from the music-light generating means resonate to enhance hearing and overall sound output.

Abstract: A light pen with multicolor light sources comprise a pen holder and a pen body wherein the pen body which slips on the pen holder can generate multicolor light sources, and the pen body further comprises a multicolor Light Emitting Diode (LED), a housing, and a conductive stand wherein the LED and the conductive stand are installed respectively at both ends of the housing. By turning the knob on the conductive stand, the conductive piece therein timely contacts the positive leads of different chips of LED in order to make the multicolor LED timely generate multicolor light sources to facilitate the convenient usage of light pen.
