Must be a malfunction to landing gear lights, as it reported the landing gear down and locked when it reality it's probably down but not locked, and as a result when the plane landed the front landing gear snap off.
Had there been an indicator light issue, the crew would of definitely try to fix it first (the CVR will tell if that is the case), and even if they are low on fuel, the flight crew will notify ATC that they need assistance because of abnormality with landing gear indicator. So far, no report that ATC received such request.
