INDICATOR LIGHT DEVICE
An indicator light device includes a circuit board, at least two light-emitting components, a light-guiding plate, and a housing. The light-emitting components are disposed on the circuit board and are spaced apart from each other. The light-guiding plate includes a plate body disposed on the circuit board, and at least two light-guiding members extending from the plate body in a direction away from the circuit board and corresponding respectively in position to the light-emitting components. The plate body has a surface adjacent to the circuit board and formed with at least one groove that is disposed between the light-guiding members and that defines a fluid space for receiving a fluid transmission medium. The housing is formed with at least two through holes, and is disposed on the plate body of the light-guiding plate such that the light-guiding members respectively extend into the through holes.
