A circuit board module has a circuit board, a first light emitting diode (LED) mounted to the circuit board, a second LED mounted to the circuit board, and a light pipe assembly disposed adjacent the first and second LEDs. The light pipe assembly is configured to convey light from the first and second LEDs to a viewing area (e.g., a front panel, a faceplate, etc.). The light pipe assembly includes a first light pipe associated with the first LED, a second light pipe associated with the second LED, and an opaque sleeve configured to fit around at least a portion of the first light pipe and inhibit light conveyed through the second light pipe from bleeding into the first light pipe. Such a sleeve is further configurable to prevent each light pipe from inadvertently capturing light from the wrong LED.
