Genuine Motorola Spiral Light Pipe for Volume and Select Controls
The Motorola 6164056H02 is a specialized spiral light pipe assembly designed to illuminate volume and selector control knobs on Motorola two-way radio equipment. This innovative optical component features a unique helical design that wraps around rotary control shafts, routing LED illumination from the circuit board through a curved light path to the control knob surface. The integrated VHB (Very High Bond) adhesive backing ensures secure attachment to the control mechanism, while the precision-molded clear material provides excellent light transmission for enhanced visibility of controls in low-light operating conditions.

Application and Installation Notes
This spiral light pipe represents an elegant solution to the challenge of illuminating rotary controls in radio equipment. The helical design allows LED light from a stationary source on the circuit board to be transmitted through the curved path and distributed evenly around the circumference of a rotating control knob. As the user turns the volume or selector knob, the illuminated ring remains visible from all angles, providing consistent visual feedback regardless of knob position. The VHB adhesive creates a permanent bond between the light pipe and the control mechanism, eliminating the need for mechanical fasteners that could interfere with light transmission.
Installation requires careful attention to alignment and should be performed by qualified radio technicians. Begin by disassembling the radio to access the volume or selector control assembly. Clean the mounting surface thoroughly with isopropyl alcohol to remove any oils, dust, or residue that could compromise adhesive bonding. Remove the protective backing from the blue VHB tape, being careful not to touch the adhesive surface. Align the four mounting posts with their corresponding holes in the control assembly, ensuring the keyed central opening matches the control shaft orientation. Press firmly to activate the VHB adhesive bond, applying even pressure for 10-15 seconds. Allow the adhesive to cure for at least 30 minutes before reassembling the radio.
This light pipe should be replaced when troubleshooting dim or non-functional control illumination, when the original light pipe becomes damaged or discolored, or when adhesive failure causes the component to separate from the control mechanism. Common symptoms requiring replacement include uneven knob illumination, dark sections around the control perimeter, complete loss of control lighting, or visible damage to the spiral structure. Handle the new light pipe carefully to avoid fingerprints, scratches, or contamination of the optical surfaces. Never attempt to reuse the VHB adhesive or clean it with solvents, as this will compromise bonding strength.
Perfect for authorized Motorola service centers, professional radio repair technicians, and communications equipment maintenance facilities servicing mobile and portable two-way radio systems used in commercial, public safety, and industrial applications.
