Whats coming out the back of the lights? Might pay to start from the back end and work your way to the front.

Sounds like they have run 2 cables back to the front rather than splitting one. My guess is
2 red wires together to no. 6 for brakes.
2 brown wires together to no. 7 for tail lights
1 yellow wire from LHS to no.1 for left indicator
1 green wire from RHS to no.4 for right indicator
2 white wires together to no. 3 for earth.
The rest do nothing.

I think that's how it would go. If you see smoke its wrong. ;-) The Narva link above sets it out. Be wary of shorts in the cables, dodgy previous work and I have also had a LED that was wired wrong from the factory. A bit of liquid electrical on connectors makes them last a lot longer.

Poor earth / chassis contacts causes Christmas tree effects. Make sure you double check earth/ normally black wire integrity. Wire colors can be different but green by standard is right indicator, yellow is left, red is stop, white are ?". Dang can't recall right now :sleep: but that probs points to poor chassis earth, more likely from the output harness of the vehicle itself.
It is not a short circuit, a short will blow your fuse or fuses related to the circuits. Earth wires , don't,get shorted, they'll just create bad power loops.
Btw, double checking earthed points, means derusting, retighting screws and bolts related to that earth point .

chek the fuse for your tail lights on the car, my triton has a separate fuse for the tail light under the bonnet, its in a few cars for some reason, same thing happened to me , no trailer tail lights/ parkers, and that was the problem, your car tail lights will work but not your trailer..
