What causes trailer lights to blink?
All Trailer Lights Blink When One Turn Signal Is Activated. The most likely cause for the incorrect behavior of your trailer lights, where activating one turn signal causes all trailer lights to blink, is an insufficient ground (or a short to ground) on either the vehicle or the trailer.
Why does both lights on my trailer flash when I turn the turn signal on?
Both Trailer Turn Signals Blink at the Same Time This is normally related to a bad ground connection somewhere. Make sure the main trailer connector ground and the grounds for each of the lights are all connected to clean and corrosion free bare metal surfaces.
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.
Is there a turn signal for both left and right?
Although some models use a separate light for the left and right turn indicators, other models use a single light for both turns. If your instrument panel has only one indicator light for both left and right, check the flasher unit. Some vehicle models combine the brake light, taillight and turn signal into one light bulb.
Where does the power come from for trailer lights?
A: This wire provides the power to the trailer lights. Green = right turn, yellow = left turn, red = brake, and brown = taillights. These are going to the power converter and are only used as a signal. Once a function is used on the vehicle, the converter provides the actual power for the trailer lights from the battery.
When do you add trailer lights to your vehicle system?
A: When you add trailer lights to a vehicle system, the turn signal amp load basically doubles. Most vehicles have a flasher that controls the blink of a turn signal. The standard flasher provided in many vehicles will not handle this extra load.

Why do my trailer lights blink at the same time?
If you find that the signals are incorrect coming out of the converter then the converter has gone bad and it will need to be replaced. If the signals are correct coming out of the converter to the 4-Way then the issue is on the trailer side wiring. You will need to check the grounds at the trailer connector and the trailer lights.
