What gives, are the newer 1154s wired in reverse compared to the older ones? Anyone else run into this issue?
... duh ...
Revelation.
The bulbs themselves are reversed wired according to vehicle POS or NEG GRD.
I learn't something new today. I did not know that and of course, it took a while to settle in but I learn't something.
My 3rd grade education (two tours) is finally starting to pay off ...

Wild, I thought they just used glass fuses, are those like internally melting (one time usable) elements?
