Hitch the trailer. Connect the lights. Start your car or truck. Turn the turn signal on. Get out and go behind the trailer. See if they blink. Repeat for the other side.

To repair boat trailer lights, first check the bulbs and replace any that are burnt out. Next, inspect the wiring for any frays or corrosion, ensuring all connections are secure and clean. Use a multimeter to test for electrical continuity and voltage at the light connections. If issues persist, consider replacing the entire wiring harness or the light assembly itself.

OK, if the left turn signal light flashes on the trailer when you hook it up I would pretty much think it has to be the bulbs or sockets are bad in your truck. I'd put a new bulb in and seee what happens before anything else. If no help, pull one of the bulbs and put a test light in there and see if it flashes.
Check the wiring for damage or grounding problems and thoroughly examine the trailer plug if you have one. If you can't find any problems there, check the turn signal switch.
The 4 pin connector should have 4 colored wires. They are: Yellow - Left Rear Stop and Turn Signal Green - Right Rear Stop and Turn Signal White - Chassis Ground Brown - Tail / License and Running Lights If you are matching a vehicle to a trailer, be sure to verify this with a test lamp or meter. Some folks make up their own rules, and the connector could be wired differently from the standard!
To install trailer lights on a 2003 Mazda Tribute, first, locate the vehicle’s wiring harness under the rear bumper. You'll need a trailer wiring harness kit designed for the Tribute, which typically connects to the vehicle's existing wiring without splicing. Attach the harness by matching the connectors and securing them as per the kit instructions. Finally, mount the trailer lights and test them to ensure proper functionality.
To fix signal lights, first, check the bulbs to see if any are burned out and replace them as needed. Next, inspect the wiring and connections for any signs of damage or corrosion and repair or replace as necessary. If the signal lights are still not functioning, test the signal relay and the fuse associated with the lights, replacing them if they are faulty. Finally, consult the vehicle's manual for specific troubleshooting steps or seek professional assistance if issues persist.
To test a trailer harness with a multimeter, first ensure the vehicle is connected to the trailer and that the vehicle's lights are on. Set the multimeter to measure DC voltage and probe the appropriate pins on the trailer connector based on the wiring diagram for the harness. Activate the turn signals, brakes, and running lights one at a time to check for the correct voltage at each pin. If the readings match the expected values, the harness is functioning properly; if not, there may be a fault in the harness or vehicle wiring.
Assuming you'll be using the common four pin flat connector; Green is Right Turn signal/brake light Yellow is Left Turn signal/brake light Brown is for Tail lights/Running lights White is Ground You may need a 12volt test light to identify the wires on the truck to identify which ones to splice into. Connect to a good ground and pierce the insulation with the pointed tip to identify.
Back track on your connects and ground wires. I bet that does the trick. If not test your sockets and fuses. fasttony46@yahoo.com
