Narrative:
We were flying a visual approach. I was the PF; and we were configuring normally for a visual approach. I called for flaps 25; was pausing to call flaps 30 and noticed the le flaps transit (amber) light illuminated. We looked overhead and noticed the #1 le slat was not indicating extended. The captain looked out and saw it actually was extended. We had a short conversation and decided the safest course of action was to land as we were confident of our configuration of gear down; flaps 25; and all leading edges extended. The landing was uneventful; and we debriefed our experience as we waited for maintenance to defer the le indication for our return flight.
