Tried two tests this morning with inconclusive results:

1. Switched the parking light leads and the flasher leads on both rear sockets with the leds in case they are oriented 180 deg opposite of 1157 bulbs.

Key on, turn signal on - everything operated correctly. Before switching - all 4 lights flashed including trunk lights.

Key on, parking light on, turn signal on - the fronts flash but the rears don't. All leds on the rear bulbs were illuminated. Before switching - all lights worked and operated correctly.

2. Pulled trailer relay fuses:

Key on, turn signals on - turn signals flashed only at front

Key on, parking lights on - all lights came on, only led units associated with parking lights were lit in rear.

Key on, parking lights on, flasher on - all lights came on, only leds units for parking light lit, only front lights flash - nothing flashing at rear.

Anything?
