B737 first officer reported red gear down light with aural warning during gear extension.

Narrative:

On approach to landing in ZZZ for runway xxl; when the gear was selected in the down position we heard an aural warning indication and subsequent warning light. The aural warning and light came on during landing gear down transition; that's when I noticed the red gear down light indication that was in the process of transitioning to three green. I at first thought the aural warning and light was a false indication for landing gear lights; but the three green down illuminated properly. During the successful completion of the landing checklist is when we then identified the red wheel well light had illuminated; and the reason for the warning bell aural indication and light. The wheel well light checklist was called for and indicated if gear down land as soon as possible. Approaching 1;000 feet it was determined the best course of action was to continue and handle the possibility of a fire on the ground. The landing was completed with no problems; and on landing roll-out we asked for arff (airport rescue and fire fighting) to come and look at the airplane.as we taxied off the runway to a position that was determined a safe reasonable place for arff assistance we again reviewed and completed the wheel well light abnormality checklist in the QRH. The flight attendants were requested to do a walk through for smoke odor or abnormalities; and they indicated all seemed ok. A call was initiated with ATC. Arff then established communication with us and was asked to complete a wheel well scan for a possible fire/smoke/heat issue. After arff completed their checks with no indications of fire/smoke/excessive heat it was determined the aircraft could be safely taxied to the gate with them following us to park. At the gate arff re-indicated there was no excessive heat issues or problems; maintenance was on board and was going to do their job since we wrote up wheel well light illuminated on gear down transition in [a logbook] entry. There were no further issues and the flight was considered completed.
