An LED module may include at least one LED and an indicator. The indicator may include one or more diffusing surfaces defining an angular diffusing groove. The diffusing groove may receive the LED such that the LED is at least partially located within a volume space defined by the one or more diffusing surfaces. The diffusing groove may diffuse a light emitted from the LED and incident on the one or more diffusing surface of the diffusing groove such that the light is diffused into an interior of the indicator.
