A power amplifier of the kind adapted to drive a speaker of a sound system and having a light-up handle at each of the opposite sides thereof. Each light-up handle is preferably a rod or cylinder that is manufactured from a light transmitting plastic (e.g., acrylic) material. A plurality of light reflective bubbles are randomly distributed in the plastic material to enhance the visual effect produced by the light-up handles. Each end of each handle has a cavity formed therein. An LED is located within each cavity so that a pair of LEDs at opposite ends of a handle will face one another in spaced axial alignment. The LEDs are energized by a DC voltage so as to inject beams of light longitudinally through the handles from opposite ends thereof. Accordingly, the handles will be illuminated to produce an ornamental, aesthetically pleasing neon light effect that will be visible to onlookers through the light transmitting material of the handles.
