Allen,
Looking at our 2006 PT, I just discovered that not only is the label for PCB#8 printed wrong (HI vs LOW BEAM), but it is 180 degrees off. This makes diagnosing very confusing. The corrected label is also 180 degrees off, the letters ‘F8’ need to go to the bottom.
LEDs per schematic
D4: RED – HI BEAM CRKTBRKR OK
D5: GREEN - HI BEAM RELAY OK
D1: RED – LOW BEAM CKTBRKR OK
D2: GREEN – LOW BEAM RELAY OK
D3 YELLOW – LOW BEAM SIGNAL OK
Looking at the images that you posted, it appears that the first image is correct for high beam (D4) on, low beam (D2) off, the second image would be correct for low beam (D2) on, high beam (D4) off.
I would next use a DVOM to take readings at the J1 terminal block on PCB#8. I posted the pin outs for J1.
Then, depending on your results, follow the suggestions in the above-mentioned thread. You could also report back your results.

I forgot about this, back wall of the front run box, up high and to the left is a terminal strip (TS1). The left most terminal is low beam output. I think that this would be the easiest to check for low beam power before it goes through the bulkhead.
