Video Transcript for Review of Diamond Lights - Load Resistors - DI34ZR

Jeff: Hello everybody, this is Jeff at Today we're going to take a look at the 50 watt load resister kit for the LED turn signals. It is for a quantity of two resistors. Now these load resistors will prevent hyperflashing on your turn signals with LED bulbs. It's designed to work with most import and domestic vehicles. You can see they are a nice compact design.

They'll fit into tight spaces. These are compatible with 12 volt DC systems. They will surface mount behind your vehicle headlights and the connection plugs are included. The quick connect plugs, which will let you easily connect to your power source. A few specs again, it's two load resistors.

Wattage is 50 watts, electrical resistance is six ohms, and last thing I want to do is just give you dimensions on the resistor. The length on it, right at two inches long. The width, including the mounting brackets, it's right at one and a quarter inches wide. And the overall height of it is right at 11 16ths of an inch tall. But that should do it for the review on the 50 watt load resistor kit for the LED turn signals..

They didn't solve my problem my trailer lights still flash and in fact I had ti remove them because they made the problem more pronounced.

I wanted to ask how you had installed them? We have a great question on the site that can help. Please see the link below.

Converted recently to LED lights on my 2008 Dodge Ram 2500. Although the manufacturer assured me the LED replacement lights were simple plug-n-play & thus did not need resistors to prevent hyper-flash… WRONG, rear signals did not play well w/ others. Jesse M identified the correct resistor set, shipping was fast & the frustrating hyper-flash eliminated immediately. Thanks Jesse!


This product fixed my trailer LED light issues while connected to my 2020 Silverado HD. I used 1 of these on each circuit to place proper load on circuit so that the truck would recognize the trailer was connected and allow the lights to function properly.


LED Rules!


It was easy to install the resistor with quick connect clips, I wish there was some instructions with the packaging. I didn't know if it matters what side of resistor was connected to positive. I decided to just install them and fixed my hyper flashing the new led tail lights.


This is the second set I ordered. I replaced all my lights on my Toyota with LED's and the hyper flash issue came to light. I knew a resistor would work but didn't know exactly what to get. I called and as usual, etrailer was extremely helpful. The customer service lady suggested what to purchase and I did. The resister set arrived early which was wonderful, however in packaging they pretty much weaken the wiring as they fold them over to get them in the clam shell. Both resisters look pretty frail and I fear the wires will break eventually. I went ahead and installed them and unfortunately they only fixed my hazard lights, turn signals still hyper flash. I ordered a second set to put one at each corner. The packaging was the exact same. GGGGRRR. I have not installed these yet but I hope they fix my problem and the wires do not break. The set is affordable but my only complaint about etrailer is the shipping. I have had instances where it's cheaper to keep product then to return it.


Took care of the hyper problem.


Easy to hookup. Was on time.


Quick processing & shipment. Product was also packaged well.

  • Will an Bulb for 2006 Dodge Ram Pickup Need a Resistor
    If you replace the lights in your 2006 Dodge Ram with LED bulbs you will need a resistorif the bulb is to be used as a turn signal. If it is to be used as a tail light only, the resistor will not be necessary. I recommend the Diamond LED Light Bulb Load-Resistors # DI34ZR. It guards against LED-related turn signal problems and is a simple, effective system that builds resistance that corrects flash timing, therefore preventing the hyperflash that can occur with LED indicators. I have included...

  • Should Load Resistors be Grounded to the Vehicle Frame or an Existing Ground Wire
    The ideal location to ground anything would be to the metal frame of the vehicle in the nearest corrosion free bare metal surface. However, if there is a ground wire near by you could try it out and see if it offers a sufficient ground. If you still get hyper flashing then a better ground location could be needed. I have included a link to the installation details for the load resistor # DI34ZR for you.

  • How to Fix Rapid Turn Signal Flashing On a Vehicle
    It sounds like you may be experiencing a hyper flashing issue. This can occur if you add LED lights to a vehicle that normally uses incandescent lights. The fix is to use load resistors, like # DI34ZR, on the turn signal circuits. This extra bit of load will stop the hyper flashing from occurring.

  • Installing LED Light Bulb Load Resistor Kit
    Each bulb should have a power wire and a ground wire. As you can see in the diagram I provided, one lead of the resistor is tapped into the power wire, and the other lead of the resistor can either ground to the vehicle or tap into the ground wire from the lamp.

  • Should Load Resistors Prevent Hyperflashing
    LED lamps draw only a fraction of the power that an incandescent lamp would. If the vehicle has a bulb-out sensor, the turn signals will blink rapidly, or hyperflash because the vehicle thinks you have a burned out bulb. Using a properly installed load resistor will eliminate this problem. If the resistor is incorrectly installed, the lamp will still hyperflash. I've provided you an install diagram showing the proper installation of the load resistor. Review your installation to make...

  • Troubleshooting LED Turn Signal Malfunction On 2011 Nissan Sentra
    It sounds like there may be a problem with the load resistors somewhere in the wiring. If they are not grounded securely they can cause problems like you said you are having. I have attached a drawing that shows how load resistors should be installed you can check out. If you are still having the problem with the one time turn signal and then nothing, you might want to check the output side of the resistor wiring with a multi-meter to make sure you are getting sufficient current for the...

  • Troubleshooting Putco 3157 LED Lights on a 2012 Dodge Challenger
    Since you are experiencing hyper flashing with your LED lights, using a load resistor like # DI34ZR per affected light is correct. However, I would remove the 4 load resistors you added to the rear center lighting. I recommend using the LED load resistor # DI34ZR because it's 50 watts. Replace one first and see if it helps. If it helps the sync problem, then use this load resistor for each light. A load resistor can become hot because it is designed to hold back power. Wrapping them...

  • Are Load Resistors Needed on a 2010 Nissan Rouge when Installing LED Blinkers
    Yes, you will need a Load Resistor, item # DI34ZR, at at least two lights that you plan to install on your 2010 Nissan Rouge, if after installing the LED blinkers you have a hyperflash situation. If you still have hyper flash with two resistors installed you will need to install 2 more resistors at the other lights. You should install the LED blinkers first to determine if the resistors are required on your vehicle. You will not need to calculate the Ohms, the resistor is built to build...

  • How Do I Install Load Resistors for the LED Lights on my 2007 Dodge 3500 Flatbed
    You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes, blinkers, or emergency flashers are operated. To do this correctly, you will need to wire the load resistor on the positive wire and then either ground it to the ground wire of the bulb, or to a good frame ground. You will need to do this for all of...

  • Lights Going Dim when Running Lights are Turned On After Adding an Incandescent Light for Resistance
    Adding an extra incandescent light is an acceptable solution for issues encountered when LED lights are added to a vehicle. The additional light adds resistance, as you have noted, to eliminate turn signal problems, much like the LED load resistor, # DI34ZR, that you referred to. If your vehicle is equipped with LED lights from the factory there should no need for an additional light or a load resistor. You may have a ground issue since the signal and brake lights are dim when the running...

  • Are Load Resistors Required When Installing LED Lights on a 2010 GMC Acadia
    You would only need to install a load resistor, like # DI34ZR, at each light if you were experiencing a hyper flash issue (rapid light blinking). This is normally only found on turn signals though. I have included a link to all of the exterior lights we carry for a 2010 GMC Acadia.

  • Turn Signals Hyperflashing on a 2011 GMC Sierra Denali 3500HD
    As you probably know, adding LED lights can cause a hyperflash problem with turn signals. You would need to add a load resistor like # DI34ZR to every light that was changed to LED. You have to make sure that the load resistors are installed correctly. One wire will connect to the power wire going to the bulb. The other wire you will ground to the truck frame or grounding point. I have included a picture that shows how it should install.

  • Is a Load Resistor Needed On All LED Lights that are Hyperflashing
    If you are experiencing a hyper flashing situation with the LED lights, you would need to use one load resistor, such as # DI34ZR, per affected circuit. The load resistors will increase the power draw so the vehicle does not think there is a bulb out or going out. I have linked a video showing an installation for you.

  • Hyperflash On 2009 Ford Flex After Installing Trailer Wiring
    It sounds like you have a hyperflash condition with your 2009 Ford Flex. LED lights will flash like that because they do not provide enough power draw for the system to recognize them and the vehicle bulb-out sensor thinks there is a bulb out on the circuit. You should start by reinstalling the T-One to make certain all connections are seated properly and not causing the problem. If all of the connections are good and you have LED lights on your trailer, you may need Diamond LED Light...

  • Are Load Resistors Needed for LED Backup and Brake/Tail Lights
    When changing from incandescent or halogen type bulbs to LEDs, load resistors are required. For the blinker circuits you can use load-resistors like the Putco LED Light Bulb Load-Resistors # DI34ZR to prevent hyperflashing of the blinkers. This kit includes two resistors and connectors for installing a pair of bulbs as turn signal lamps. Check out the installation instructions I have attached for part # DI34ZR. I have also included a link to our exterior LED automobile lights for you...

  • Troubleshooting LED Trailer Lights that Flicker When Vehicle is Off
    What you are experiencing is due to the fact that LED taillights only require a very small amount of amperage to illuminate. A tiny amount can cause them to illuminate. Trailer wring for the most part goes totally dead when the vehicle is off. But there can be small amounts of voltage that would normally not get noticed if the trailer had incandescent bulbs. It really isn't a problem unless it bothers you. The flickering wouldn't be enough to drain your battery. But if you want it to stop...

  • Add-On LED Turn Signals are Hyper Flashing on a 2007 Cadillac SRX
    The hyper flashing might stop if you put them on all turn signal circuits, including the front ones. And it may not. Since this is a non-standard set up it will take some trial and error to determine what the problem might be. If you have the load resistors grounded to the same ground as the light I recommend moving it to its own ground location specifically to a clean and corrosion free bare metal surface with no paint or coating. If you have the resistors grounded separately already...

  • Do Putco Ceramic Load Resistors P230004C-2 Get Hotter than Aluminum Load Resistors 230004A-2
    All types of load resistors such as part # DI34ZR will get hot as they do their job of absorbing power (providing resistance). Both will work fine for helping a wiring harness work well with low-power-demand LED type trailer lighting. Aluminum will disapate heat faster, however, all will get the job done. .

  • Are Load Resistors Needed When Converting Incandescent Taillights to LEDs
    If the vehicle has bulb-out sensors, you'll want to use load resistors on each turn signal circuit to prevent hyperflashing. Because LED lamps draw so much less power than an incandescent bulb, the bulb out sensor thinks the bulb is burned out. The load resistor adds resistance to the circuit, which simulates a full load on the circuit. Hazard flashers use the turn signal bulbs, so the same two load resistors will cover that, as well. I've linked you to the install diagram for the load...

  • New Amber LED Lights Flicker on a 2000 Cadillac Escalade
    It sounds like there is a bad connection or ground or there isn't a load resistor on the running light circuit, Usually load resistors are used to cure hyper flash on a turn signal. But since LED lights draw such little power it could be that another load resistor is needed such as # DI34ZR. This is especially true if it is happening on both sides. If the issue was one side I would say there is a loose connection or bad ground.

  • After Installing Load Resistors Brake Lights Come On and Turn Signals Hyperflash with Headlights On
    It sounds like either you have the load resistor # DI34ZR connected to the wrong circuit, not connected quite right, or the vehicle uses a pulse width modulation type of wiring that could affect performance. I have included a picture that shows the 2 ways a load resistor should be installed. If you can tell me the year, make, and model of the vehicle you are using the load resistors on I can determine if there is something about that vehicle that would prohibit the use of load resistors.

  • Do Diamond # DI34ZR Load Resistors Get Hot
    Load resistors can reach between 140-160 degrees Fahrenheit. Therefore, mounting them to a plastic surface wouldn't be a good idea. Mounting them to a metal surface is recommended.

  • How to Install LED Light Bulb Load Resistor for Use with Trailer with LED Lighting
    The Diamond LED Light Bulb Load-Resistor Kit # DI34ZR wires in parallel with each trailer lighting circuit. For a trailer with LED lighting (that does not present the same electrical load as an incandescent type bulb) you will wire one resistor inline with each circuit, so for a typical 4-pole installation you'll need three, for left turn/stop, right turn/stop and running light circuits. The kit includes quick-splice connectors.

  • Does an LED Third Brake Light Require a Load Resistor
    The only circuits that need load resistors are the ones that flash when the blinkers or hazards are on. A third brake light circuit would not require a load resistor like the part # DI34ZR that you referenced.
