Narrative:
I learned of this event almost 4 months after it had occurred. I was told that I installed the wrong effectivity locator beacon on aircraft X during my emergency equipment inspection; during the B757 B check. I installed a part and it should have been another part. It was purely unintentional to put the wrong locator beacon on the aircraft. The evening after learning of the event I spoke to my B check lead technician and he said and I agreed that the B check paperwork could use some clarification. A part number on the locator beacon would surely help. Plus effectivity clarification. Even by using the parts catalog it was confusing. A misunderstanding; due to unclr paperwork. Is it possible to have part numbers put on the emergency locator beacons; as it is on most other emergency equipment?

Title: A B757-200 DURING A HVY CHK HAD THE INCORRECT EMER LOCATOR BEACON INSTALLED. AIRPLANE OPERATED SEVERAL WEEKS BEFORE DISCOVERY.
Narrative: I LEARNED OF THIS EVENT ALMOST 4 MONTHS AFTER IT HAD OCCURRED. I WAS TOLD THAT I INSTALLED THE WRONG EFFECTIVITY LOCATOR BEACON ON ACFT X DURING MY EMER EQUIP INSPECTION; DURING THE B757 B CHK. I INSTALLED A PART AND IT SHOULD HAVE BEEN ANOTHER PART. IT WAS PURELY UNINTENTIONAL TO PUT THE WRONG LOCATOR BEACON ON THE ACFT. THE EVENING AFTER LEARNING OF THE EVENT I SPOKE TO MY B CHK LEAD TECHNICIAN AND HE SAID AND I AGREED THAT THE B CHK PAPERWORK COULD USE SOME CLARIFICATION. A PART NUMBER ON THE LOCATOR BEACON WOULD SURELY HELP. PLUS EFFECTIVITY CLARIFICATION. EVEN BY USING THE PARTS CATALOG IT WAS CONFUSING. A MISUNDERSTANDING; DUE TO UNCLR PAPERWORK. IS IT POSSIBLE TO HAVE PART NUMBERS PUT ON THE EMER LOCATOR BEACONS; AS IT IS ON MOST OTHER EMER EQUIP?
