I'm just throwing this out there.
My 1974 ford pickup lighting circuit has all original wiring, sockets and T/S switch. Everything worked good with incandescent bulbs and I bought everything I needed to convert from an outfit that sells LED kits and stuff.
Everything would light and flash OK until you replaced the last incandescent with an LED. Didn't matter what socket, 3 LED's and 1 incandescent OK, 4 LED's no flash.
Tried different flashers, same problem.
I'm not an electrical wizard but I spent most of my career as electric forklift mechanic so I am at least familiar with DC circuits. I have full prints and I just could not see why it was doing this and all tests showed no issues with my wiring system.
After research I bought a set of LED bulbs that where non polarized. Put them in and everything worked great.
That was in 2018 and I've had no issues since.

These are the bulbs I used to make my system work with no modifications.
