You have a ground issue.

get the standard wiring design

Yellow is the left turn signal on pin 2
Check trailer plug and see if correct colors used on trailer plug
Would suggest getting a 12volt probe so you can test the car socket when left indicator is going on - flashing
To check that the correct pin has 12volts flashing left on it.

you have a short positive or power wire is touching the ground ,bare metal orr a wire that runs to negative side of battery . check all the plugs to all the headlights and taillights parking lites plate lite or any other thing that works on that fuse could be headlite switch

Use a volt meter or a test lite ,check for power at the bulb or on the wire to the bulb also check the ground wire to see if it supplys a ground circuit.Look for wires loose from the headlites ground circuit.If equiped it will be close by,A black wire with a screw to framework for a ground.If you have 4 hd lites make sure you dim and or brighten the lites while you look for problem. There may be a fuse for each side of the headlites right and left!

Probably bad ground connections, clean & recheck headlights!

If your signals & brakes are on 2 different circuits, ( for example a red lens for stop & an Amber for turn.) then you'll need to buy a converter that goes between vehicle & trailer. They're not too expensive at any trailer or RV place. I think some of the autoparts stores stock them now too.
