Narrative:
On the evening of dec/thu; I was called to a gate for a pilot write-up about a 'leading edge flaps transit light.' since the aircraft came late to the gate; I proceed to meet the inbound crew; but the crew was already gone. I went over the write-up with the outbound crew and we agree that I'll be calling maintenance control to MEL the system. I talked to mr X in maintenance control which asked me to read to him; exactly what was the write-up; which I did. We MEL the system and I returned the book to the crew. The airport left the gate shortly after. Neither the outbound crew nor mr X in maintenance control nor I noticed that the #4 'leading edge flap transit' light write-up couldn't be MEL. I believe the cause of this event was due to poor communication between the 3 of us.

Title: A B737-300 WAS DISPATCHED WITH THE #4 LEADING EDGE FLAP TRANSIT INDICATION LIGHT INOP AND DEFERRED IN CONFLICT WITH THE MEL.
Narrative: ON THE EVENING OF DEC/THU; I WAS CALLED TO A GATE FOR A PLT WRITE-UP ABOUT A 'LEADING EDGE FLAPS TRANSIT LIGHT.' SINCE THE ACFT CAME LATE TO THE GATE; I PROCEED TO MEET THE INBOUND CREW; BUT THE CREW WAS ALREADY GONE. I WENT OVER THE WRITE-UP WITH THE OUTBOUND CREW AND WE AGREE THAT I'LL BE CALLING MAINT CTL TO MEL THE SYS. I TALKED TO MR X IN MAINT CTL WHICH ASKED ME TO READ TO HIM; EXACTLY WHAT WAS THE WRITE-UP; WHICH I DID. WE MEL THE SYS AND I RETURNED THE BOOK TO THE CREW. THE ARPT LEFT THE GATE SHORTLY AFTER. NEITHER THE OUTBOUND CREW NOR MR X IN MAINT CTL NOR I NOTICED THAT THE #4 'LEADING EDGE FLAP TRANSIT' LIGHT WRITE-UP COULDN'T BE MEL. I BELIEVE THE CAUSE OF THIS EVENT WAS DUE TO POOR COM BTWN THE 3 OF US.
