Where is the right side turn signal on a trailer?
If you haven’t already, check the light assembly itself on the right side of the trailer. The light will either ground with a dedicated wire or through its mounting hardware – in either case, make sure it’s connected to a clean, corrosion-free piece of metal.
How to troubleshoot right side trailer lights not working?
You might apply 12V power directly to it to ensure the bulb isn’t out. Also make sure it’s securely grounded to a clean, bare piece of metal (whether it grounds through a dedicated wire or through its mounting hardware). Let me know what you find and we can keep troubleshooting if needed. 67185
Where are the brake lights and left side turn signals?
Your brake lights and turn signals for each side are on one circuit. The left side turn signal and brake light is generally the yellow wire going into your trailer connector. The first thing to do is check the fuses on your tow vehicle. Next, inspect and test the connector at the rear of your tow vehicle with a circuit tester, like # 40376.
Is the left side turn signal the same as the right?

Why are the lights on the right side not working?
If looking at the face of the connector, it is the pin in the 3 oclock position. If you are getting the proper signal at the connector, you know that the problem is on the trailer side. On the trailer, make sure the main ground is connected to a paint, dirt, and corrosion free bare metal surface on the frame.

Why is my left side turn signal not working?
The turn signal not working makes sense because with the brake lights, there is a constant signal coming through which is enough to make the lights illuminate on both sides like they should. But the on/off of a turn signal does not offer enough consistent voltage and makes the problem apparent.
What are the running lights on a trailer?
The next thing is to make sure the wires on the trailer plug is wired properly to the trailer. If you have a 4-Way connector on the trailer the white wire is for ground, the green wire for right turn and brake, yellow wire for left turn and brake, and the brown wire is for running lights. I am including a link to a FAQ page on trailer wiring.
What should I do if my trailer lights are not working?
Open them up and make sure there is no white or green corrosion causing an issue inside the connectors. If so clean them out or replace the connectors with new ones. If the problem is not found in the connectors, you will need to follow the trailer wiring and check all of the grounds for all of the lights and the trailer connector.
