Dodge Ram trucks are equipped with LED tail lights. The LED tail lights are brighter and last longer than traditional incandescent bulbs. however, they may not operate properly if the truck is equipped with a trailer brake controller.
When the trailer brake controller is used, it can cause the voltage to drop below what is needed to operate the LED tail lights. This can be corrected by installing a resistor in line with the LED tail light circuit.
If you own a Dodge Ram, you may have noticed that your LED tail lights aren’t as bright as they used to be. This is because the LED tail light resistor is failing. The LED tail light resistor is responsible for regulating the current to the LED tail lights.
When it fails, the current to the LEDs is no longer regulated and they become dimmer. There are a few ways to test whether or not your LED tail light resistor is failing. First, check to see if yourtail lights are still bright when you first turn them on.
If they are, then it’s likely that the resistor is starting to fail. Another way to test is by turning on your headlights and then turning on your taillights. If your taillights are significantly dimmer than your headlights, then the chances are good that your LED tail light resistor has failed.
If you suspect that your LED tail light resistor has failed, it’s important to replace it as soon as possible. A failingLED tail light resistor can cause problems with other electrical components in your vehicle and can even lead to a fire if it isn’t replaced promptly.
Led Tail Light Resistor Install
If you’ve ever been driving and had your LED tail lights go out, you know how frustrating it can be. Luckily, there is an easy fix for this problem – installing a LED tail light resistor. This simple fix will ensure that your LED tail lights always stay on, no matter what.
Here’s what you’ll need to do to install a LED tail light resistor: 1. Start by disconnecting the negative battery terminal. This will prevent any electrical shocks while you’re working on the wiring.
2. Next, locate the taillight wire harness near the taillights themselves. You’ll need to access the wires that power the taillights in order to install the resistor. 3. Once you’ve found the right wires, cut them and strip back about ½ inch of insulation from each one using a wire stripper tool.
4. Take your LED tail light resistor and connect one end to each of the two wires that you just cut and stripped back. Make sure that the connection is secure so that it doesn’t come loose while you’re driving.
Do I Need a Resistor for Led Tail Lights?
If you’re thinking about upgrading your vehicle’s tail lights to LEDs, you may be wondering if you need a resistor for LED tail lights. The answer is: it depends. Here’s what you need to know about using resistors with LED tail lights.
First, a little background on how LEDs work. LEDs are diodes, which means that they only allow electricity to flow in one direction. This is the opposite of traditional incandescent bulbs, which allow electricity to flow in both directions.
When an electric current flows through an LED in the wrong direction, it doesn’t light up. In order to get an LED to light up, you need to provide it with the correct amount and type of electric current. So, why would you need a resistor for LED tail lights?
It all has to do with the amount of current that flows through the LEDs when they’re turned on. If too much current flows through the LEDs, they can be damaged or even destroyed. That’s where resistors come in – they help regulate the flow of electric current so that it doesn’t damage the LEDs.
Now that we’ve covered howresistors work and why you might need them for LED tail lights, let’s talk about whenyou actuallyneedto use them. In general, if your vehicle has standard incandescent bulbs for itstail lamps and turn signals, thenyou’ll likely needto use resistorswithLED replacementsfor those bulbs(checkyourvehicle’s owner manualor aska mechanicifyou’re not sure). However, if your vehicle already hasLEDsinstalledfor itstail lamps orturn signals-orifit was manufactured after 2008-thenit probably won’t requiretheuseof any additional resistorswithnewLED replacementstail lamps orturn signalbulbs(again, checkyourvehicle’s owner manualor aska mechanicifyou’re unsure).
So there you have it – everything you need to know about whether or not you need a resistor for LED tail lights!
What Size Resistor Do I Need for Led Tail Lights?
When it comes to outfitting your car with LED tail lights, one of the most important considerations is what size resistor you’ll need. The purpose of a resistor is to limit the flow of current in an electrical circuit, and this is especially important when working with LEDs, which are sensitive to too much current.
There are a few different ways to calculate the appropriate size for your LED tail light resistor, but perhaps the easiest is to simply use a online calculator like this one from Ohm’s Law Calculator.
All you need to know is the voltage of your Tail Light Circuit (typically 12V) and the desired current draw of your LEDs (measured in milliamps). From there, the calculator will give you the resistance (measured in ohms) that you’ll need for your resistors. It’s always better to err on the side of caution when choosing a resistor size, so if you’re unsure or don’t have all of the information necessary for an accurate calculation, it’s better to choose a larger size than you might think you need.
That way, you can be sure that your LEDs will stay well-protected against any potential damage from too much current.
What Resistor Do I Need for Led Turn Signals?
If you’re looking to add LED turn signals to your vehicle, you’ll need to use a resistor to ensure they function properly. The most common type of resistor for this application is a load resistor, which is used in conjunction with the LED bulb to create the proper resistance needed for the turn signal circuit. Load resistors are available in many different shapes and sizes, so it’s important to choose one that will fit your particular installation.
In general, you’ll want to match the wattage rating of the load resistor with the wattage rating of the LED bulbs being used. For example, if you’re using 10W LED bulbs, you’ll need a 10W load resistor. Once you’ve selected an appropriate load resistor, it’s time to install it.
The first step is to connect one end of the resistor to ground (typically by soldering it directly to a metal surface). The other end of the resistor should then be connected to the positive terminal of the turn signal bulb. It’s important that this connection is made before any other wiring in the circuit, as otherwise there could be problems with voltage drop across the circuit.
If everything is wired up correctly, your LED turn signals should now be functioning properly!
How Do You Add Resistors to Led Tail Lights?
If you’re looking to add some resistors to your LED tail lights, there are a few things you’ll need to keep in mind. First, you’ll need to determine the resistance of the load (the LEDs) and the power supply voltage. Once you have those values, you can calculate the appropriate resistor value using Ohm’s law: R = V/I.
For example, if your load is 12V and your LEDs have a total current draw of 0.5A, then your resistors should be 24 ohms each. Once you’ve determined the correct resistor values, simply solder them in place on the positive leads of your LEDs. Make sure that the resistors are rated for the same voltage as your LEDs; otherwise they could overheat and fail.
Finally, connect the other end of each resistor to ground. That’s all there is to it!

If your Dodge Ram’s LED tail lights are acting up, it might be due to a faulty tail light resistor. Replacing the resistor is a relatively easy and inexpensive fix. Here’s a step-by-step guide on how to do it:
1. Start by disconnecting the battery. This will prevent any electrical shorts while you’re working on the taillights. 2. Locate the tail light resistor.
It’s usually located near the taillight bulbs or in the wire harness leading to the taillights. 3. Unplug the connector from the tail light resistor and remove it from its mounting location. 4. Install the new tail light resistor in the same location as the old one and reconnect the electrical connector.
5 . Reconnect the battery and test out your new taillight setup!
