Tail Light Wiring Color Code – What You Might Not Know

Maintaining traffic safety for other drivers and themselves is a primary priority for drivers.Due to their significance in “communicating” with other cars, the tail lights always receive extra attention and prompt repair despite their minimal involvement in the vehicle’s operating system.

If your car has this issue, you first need to take a close look at the Tail Light Wiring Color Code!

In addition to giving you helpful information about how this device operates, this post will walk you through installing and replacing it at home without the assistance of a qualified mechanic!

How Can I Find Out What Colour Code My Tail Light Wire Is?

Manufacturers typically list Brown as an acceptable color coding for tail lights.

They utilize white for the background, green for the right turn signal, and yellow for the left turn signal.

Because the Dodge Ram tail light wire color codes are well-defined, maintenance and drivers can quickly identify the function of each type of single wire.

Additionally, they can reduce the possibility that improper wiring will harm the vehicle’s schematic.

Any light and boat trailer available today contains the “four-way rope” group, which consists of these four different sorts of ropes.

In contrast, the additional blue wire (the fifth wire) in the higher-level “five-way wiring” system is linked to the turbocharger and backup lights, frequently found in trailers and campers.

An extra red brake wire for running the battery and fuse (fit for horse-drawn carriages) is part of the “six-way wiring” scheme.

The top group, known as “seven-way wiring,” is identified by the appearance of a purple wire that serves as a hydraulic coupling.

What Do You Need To Remember About Dodge Ram Tail Light Wiring Color Code Lights?

The worst-case scenarios when working with trailer wiring include blown fuses, brake lights that flash, and turn signals that reverse.

Even though they can have disastrous effects on the car, resolving the issue is not too difficult.

Verify that the signal wires listed below are attached to the appropriate item that they support:

Brown wire: rearview mirror or Tail Lights

Green wire: Turn signal light or right brake

Yellow wire: Left turn signal or brake light

White wire: Grounding or chassis

To change its speed in time, vehicles behind usually focus on the trailer’s taillights.

There is a significant chance of an ongoing collision when taillights are slow or broken since other motorists won’t have enough time to react.

Thus, under no circumstances may tow truck drivers operate a vehicle with malfunctioning electrical or illumination.

Pull over to the side of the road and call the rescue crew when you see your car’s tail lights are damaged so that repairs may be done immediately.

How Can LED Tail Lights Be Installed in Your Car?

Fitting LED lights to your four-wheeled companion is similar to replacing its lenses; it will look more individualized than before.

Furthermore, LED lights’ lifespan is greater than traditional tungsten filament tail light bulbs.

Thankfully, installing LED taillights is easier than you would assume! Follow the instructions below to make people enjoy your car’s new appearance!

First, take out the old tail lights.

Most cars have taillights that are fastened from the vehicle’s trunk. As a result, you should start by removing the taillight lock and the trunk mat from the box.

To fully disassemble the taillight, gradually loosen it little by bit. Avoid rushing, as this could lead to internal clip fixing damaging the tail light.

Second Step: Take Out the Light Bulbs

Disconnect the bulbs from any rear wiring after removing them from the taillight housing.

Use colored tape to label the turn signals, brake lights, and spare bulbs for easier identification. Any wiring error can cause your car’s tail lights to burn out or get paralyzed.

Third step: Attach the wiring to the new lights.

Attach your new aftermarket LED tail light out of the packaging to the indicated signal ground wire.

It takes little time to connect, and signal wires of the same color must typically be connected.

For instance, the two black wires join, and the available red wire connects to the LED taillight’s red wire.

Fourth step: Reinstall and Test

Once the connection is made, you need to make sure the backup lights, brake lights, and turn signals are all functioning correctly.

If an issue prevents the light from turning on, go over everything and retry the installation.

If you’re doing this work alone, use duct tape or have someone hold the LED taillights in their original place. For optimal effects, slowly tighten the screw and reposition the lamp.


How Do You Wire Trailer Tail Lights For Three Tyres?

You will likely need to use specialized instruments to verify the circuit to correctly identify 3 tyre trailer tail lights.

Recall the color codes for the tail light wires of a 2006 Dodge Ram and their intended application:

  • Red wire: Turn or stop
  • Black ground wire: Light string in motion
  • White wire: Ground wire, which must be connected to an appropriate grounding location on the chassis of your trailer.

The best action is to temporarily connect the brown taillight to the 12-volt black wire and see if the light turns on. After that, join the red and brown wires and carry on testing.

The dimmer wire should be connected to the brown light circuit, and the lighter wire should generally be connected to the green (stop/turn right) or yellow (stop/turn left) light circuit.

Ensure the white wire is grounded to a suitable surface above the trailer’s frame and the blue wire is designated mainly for the trailer brakes.

How Come Brake Lights Need Three Wires?

Because they want their LEDs to be a flexible combination that can function in every circumstance, they make them with three different colored wires.

For instance, the driver can brake and flash the lights simultaneously or drive while flashing the caravan lights.

Do Tail and Brake Lights Look the Same?

No, is the response! If you examine attentively, you will see that the brake lights on some automobiles have a brighter hue than the taillights’ dark red color, even though they share the same primary color.

Furthermore, the brake lights only activate when you apply the brake; the tail lights turn on automatically when you engage the parking brake, parking lights, or headlights.


A car that cannot notify other vehicles on the road due to a faulty rear light system most definitely does not meet the minimal criteria for traffic.

For this reason, the secret to ensuring that you and those around you travel safely is to detect and address the issue promptly.

We hope this article has given you enough relevant information about the tail light wire color code and how to fix it at home if something goes wrong with the system. I wish you success in getting the remedy!
