We were just outside the Outer Marker.... I called for landing gear down; flaps 15. The flaps went to 15; however; we did not get a green light. This is about the same time we broke out of the overcast and had visual contact with the runway. I elected to continue and land the aircraft. We used flaps 30 and I carried a higher speed. After landing; the First Officer was questioning my choice and looked in the QRH. We should have gone around and come back with flaps 15 for landing. I made the call not to go back into the overcast and land. A Mechanic met the aircraft and found the number one slat was extending; however; we were not getting the indication. The Mechanic applied the MEL and we continued. This MEL is very long and confusing. On our next landing we got airspeed warnings and stick shaker; all false indications.
I was pilot monitoring. While configuring for landing; the Captain noticed the forward amber L E FLAPS TRANSIT light illuminated and called it out. I looked up at the overhead L E Devices Indicator and saw that the Number One Slat Full Extend light was not illuminated green. I notified the Captain of this. We were currently descending via the glideslope on the visual with gear down and flaps; somewhere between 2;000 feet AGL and 1;000 feet AGL. I stated that we will need to go-around. The Captain indicated that he had been in this situation before and we were fine to land. I repeated for the second time that we needed to 'go-around' and 'work on the problem.' He again indicated we were fine. I added that I believed the QRH procedure would want us to land at flaps 15 also. The approach was continued and a flaps 30 landing occurred. Considering the safety of flight and our phase of flight; the first chance I got to open the QRH was on the ground. I showed the Captain the QRH checklist that mandated a flaps 15 landing given our situation.
B737-700 Captain elected to land the aircraft with LE Flaps Transit light illuminated after breaking out of overcast on short final. First Officer stated that a go-around was required.
