Abstract
A device carrier for an information handling system includes a latch, an interface, lights located on a front of the latch, and first and second light pipes. The latch holds the device carrier within the information handling system. The first light pipes are located within the latch, and provide light to the lights located on the front of the latch. The second light pipes are located within the interface and the latch, and provide the light to the first light pipes. The location of the second light pipes enables the same brightness of the light provided to the lights when a long device is inserted within the device carrier as compared to when a short device is inserted within the device carrier.
