No turn signals when lights on

[riverplace]

I discovered that the LED tail light strips that I installed at the top work fine, until I have my driving lights on, then the turn signals don’t work. If it was a ground connection problem where I spliced them into the bottom tail lights, then it wouldn’t happen with both? So, is it a problem with the 7 pin plug? And why do the bottom tail lights work fine, but not the top? I’m trying to decide where to start with the search. When I installed a few years ago, I spliced wires to the lights, ran them down each side of cabinet, under the corner panels to the bottom tail lights, where I spliced them again, with heat shrink connectors and liquid tape.
Thanks for any suggestions!

Continuing that logic, if the problem is with the 7-pin plug then all of the lamps would be affected. It must be either the lamps themselves, or the connections to the ones which don't work properly.
