Dunno Bro... What I can say is that we had a surprising number of Bulb and Socket problems on our 2002 coach that we bought in 2008 with OEM Bargman incandescent rear lights.
Speculation:
1. The assembly may be expensive for all it really is, but it's made cheaply compared with what an automaker provides. Proof of this is the FRONT lights in our Ford E-450 Van "Nose." Never had a bulb go out or a connection corrode.
2. I believe Cheap lets Moisture in. That corrodes Socket, Bulb Shell, and related Contacts. It also seems to penetrate the bond between Glass and Shell in the Bulbs. Many of our bulb failures looked like Air or Moisture was INSIDE the unbroken Glass Envelope.
So... Spent $100 on new LED assemblies, connectors to crimp, stainless screws to mount and butyl tape to seal.
Solved... Bulbs, Sockets, Dim Rear Lights.
Worked for me. YMMV
