And so…. Did both LEDs work correctly? Yes.
Resistance was around 14ohms.
I checked the wiring again and this is where it gets weird! HE0 has been working perfectly yet ok closer inspection it's GND was in the HE1 terminal? HE1 was obviously wired vice-versa. Swapped it all around and it now all works?
Problem solved. I am interested in why it worked with HE1?
