2019 Big Horn Ram rear LED signal lights are all working but dim.

The dash board warning and dim LED lights started about 7 months ago. Strange thing happened a couple days ago. I hit 2 deep potholes which caused my negative cable to completely dislodge from the negative battery post but it was pressed up against the post with a bit of pressure, so, there was connection albeit weak. However, the turn signals worked correctly - they were bright again and clicking at the proper slow rate. When I secured the cable back onto the battery post, I got the same warning on the dash (Signal Lights Are Out) and the LED turn signal lights are dim once again. All other lights are working properly. The rear lights are a sealed unit.

Check inside of the clamp and might need cleaning. That's only thing I can think of.
