5 wire to 4 wire trailer light converter

I have an Class A Diesel Pusher RV with separate signal lights, and my trailer does not. I have installed a Reese trailer light converter Walmart $21) to remedy this problem.
The first converter lasted 5 years. The second lasted less than a week. (Currently, it works intermittently.) I need to have brake lights.
Everything works correctly: trailer brakes and tail/clearance lights.
Anyone had this issue?
Wife follows in a car, that is how I know they are working intermittent.
Thanks in advance!

    Sounds like a bad or broken connection........probably inside molded piece.

    Just buy a new adapter

    I would verify the connections. It could be a corroded or poor connection to the tailight converter on the input or output.

    Check the ground connections on both the trailer and the RV. It will be the white wire on both ends. With a bad ground on either side, the circuit will try to complete the ground thru the hitch frequently causing an intermittent signal.
