Choose a visible alert for a task with no progress estimate

Status Light is a red, amber and green desk indicator that needs a software integration to represent task activity. Some tasks expose a running state and a final result without a meaningful progress estimate. A visible alert can still be useful in that situation. Base it on what the source actually reports rather than inventing a percentage or finish time to make the signal feel more informative.

Which states can the source establish?

Inspect the documented lifecycle of the selected task. You may be able to distinguish queued, running, awaiting input and completed even when there is no progress counter. Keep the final outcome separate from completion so a failed task does not receive the same meaning as a successful one accidentally.

Record the task identity and attempt alongside its state. A delayed event from a previous run should not describe the current work. The physical signal needs a clear scope, with a source reference available when you want more detail.

What should the waiting signal mean?

Choose a plain convention such as selected work remains active. Do not imply steady advancement if the source only confirms that the process has not ended. A running task can spend time waiting on dependencies without exposing enough information to estimate remaining work.

Avoid deriving a completion percentage from elapsed time unless the source provides a valid model for that calculation. A previous task's duration is not a guarantee for the next one. A modest state signal can be more honest than an apparently precise prediction.

How can silence be distinguished from lost contact?

Use freshness or liveness evidence appropriate to the source. An event-driven job may emit nothing for a legitimate long period, so absence of an update alone does not prove a fault. A separate source check or bridge-health indication may be necessary.

Keep stale information visibly uncertain through a supported convention or companion text. Continuing to show the last state without qualification can imply current knowledge after the integration has stopped working. Confirm available device-control capabilities before planning flashing patterns or other output effects.

What should trigger attention at the end?

Choose the result or input request that leads to an actual next step, such as reviewing output or inspecting an error. Provide a route to the authoritative task record. The light should direct attention without replacing the evidence needed to assess the outcome.

The Status Light listing describes the physical device. A useful alert for an uncertain-duration task communicates verified state and freshness, while leaving progress estimates absent when the source cannot honestly supply them.
