• How to Keep LED Turn Signal Lights on Toolbox From Flashing with Brake Pedal Pressed
  Hi Richard! It sounds like you're needing to install the Load Resistor Kit for LED Turn Signals # DI34ZR on the turn signals you've installed on your toolbox. Since LEDs don't require as much power as incandescent bulbs, sometimes we see some power "leak through" and cause the LED lights to flash like what you're experiencing. The resistor kit makes the LEDs "look" like incandescent lights to your wiring system so this kind of thing doesn't happen.

• Load Resistors to Fix Rapid Flashing LED Lights
  The LED taillights often have this hyperflashing issue. To solve it, you simply need to add a load resistor like # DI34ZR. You will need one resistor for each side and this kit comes with 2. This will draw more power from your system so you won't get that hyperflashing. I've attached a diagram on correctly installing these load resistors.

• Solution for 4-Way Adapter With Resistors for 2025 Bronco Sport & Kuat Piston Pro-X With LED Lights
  Hey Stephen! There are no direct adapters but we can pair two together to make this work. You can plug the Hopkins Plug-In Trailer Connector Adapter # HM54RV into your 4-way which will convert it to just the light functions on a 7-way. Then plug the Curt # C35FR into the 7-way end of that adapter to get the load resistors and stop the warning on your dash. The only other option would be to directly wire in load resistors # DI34ZR. Let me know if you need anything else.

• Load Resistors to Allow Wiring Harness to Operate with LED Trailer Lights
  LED type trailer lights use very little power, about one-tenth the amount required by standard incandescent light bulbs. This can cause some wiring systems to not "see" the trailer lights because their current draw is so low. In some cases a wiring harness may not function correctly if used with LED lights unless a load resistor is installed at each LED light unit. We offer 2-piece ceramic load resistor kit # DI34ZR which will allow your harness to operate properly with LED trailer lights....

• Is there a 7-Round Trailer Connector Adapter for Pulling a Trailer w/ LED Lights?
  Hey William. I have a solution for you but there isn't a simple adapter like item # 20142 in 7-way round configuration. Instead you will need to install the Load Resistor Kit for LED Turn Signals item # DI34ZR on all of the taillight circuits of your trailer that have LEDs. LED lights don't draw as much power as incandescent lights so a resistor is added to increase the amperage draw to resemble incandescent lights. What kind of trailer are you pulling? You can add this information,...

• How To Install The Curt Auxiliary LED Indicator Lights C53201 With Load Resistors DI34ZR
  To wire the Load Resistor Kit for LED Turn Signals # DI34ZR into your vehicles turn signals you will need to find your turn signal wire for your vehicle. Once that wire is identified, take the one end of the wire and the turn signal wire and connect to the quick splice connector. Make this connection by crimping the wires together with a crimping tool like # PTW30764. From here you'll connect the other white wire and ground this wire to a good ground source. The Curt Auxiliary LED Indicator...

• Are Load Resistors Required when Adding LED Lights to a Trailer
  You may not even need load resistors to switch to LED lights. The best thing to do is to try the lights without load resistors first. No need to purchase something you may not need until you know need it. Load resistors such as # DI34ZR dissipate heat through the body of the resistor. Wrapping them with insulation would prevent them from dissipating heat properly. You could put them in a battery or junction box though. Load resistors increase the amperage draw on a circuit. If you are...

• 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.

• Troubleshooting Hyper Flashing Trailer Lights on Mercedes-Benz Sprinter Van
  The hyper flashing due to LED lights on your trailer is often solved with the 7-way adapter you mentioned the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142. The issue is often that LED's pull so much less power that the computer systems don't know how to accommodate the small electrical load. What I recommend doing next is checking each ground connection to ensure you have a bare metal to metal connection. Then if you still have issues,...

• Why Would Load Resistors Need to Be Installed on Trailer Lighting Circuits and Not Brake Output
  I wish it was that simple but putting a load resistor on the brake output circuit of your 7-way would not prevent the issue you are having. The error message is due to lower amperage draw of the trailer lighting circuits and not the trailer brakes.

• Recommended 3 to 2 wire Converter for Adding in a LED Third High Brake Light
  Hey Pete, so to add a third brake light that uses two wires to your 3 wire system you're going to need to use # 118158 to splice into your combined right/stop and left/stop wiring, then connect your 3rd LED brake light to the stop output on the converter. If there ends up being some hyper flashing you'll need to add in the Load Resistor Kit for LED Turn Signals # DI34ZR between the converter and the light, which will create a stronger draw like incandescent lights.

• Correcting Hyperflashing After Installation LED Taillights on 2004 Dodge Ram 3500
  In order to stop your turn signals and brake lights from hyperflashing with your LED taillights, you will want to install LED Light Bulb Load-Resistors on the turn light and brake signal wires. Hyperflashing is a common issue when changing incandescent bulbs to LEDs. One of my fellow Experts put LEDs on his Dodge 2500 and ran into the same issue. He used the #DI34ZR Load-Resistors on his truck to solve the hyperflasing issue. I've attached an installation video of these load resistors...

• Turn Signal Hyperflash on Tow Vehicle Towing a Boat Trailer
  It sounds like you have experienced a hyperflash condition. LED lights will flash like that because they do not provide enough power draw for the system to recognize them. Also, you should not mix LED and incandescent lights on a trailer. If the vehicle has LED lights and the trailer has incandescent lights then as long as the vehicle has the proper converter installed or has the factory wiring harness it should be fine unless it is the factory harness on a German vehicle like a BMW or...

• Trailer Lights Blinking Really Fast When Connected to 7-Way on 1997 GMC Yukon
  When someone is experiencing out of control or hyper flashing turn signals, a few things come to mind. First would be, does the trailer have LED lights? If so, installing load resistors, # DI34ZR, on the turn signal circuits should solve the problem. LED lights only draw a fraction of the power that an incandescent light would so vehicles with a bulb-out sensor are tricked by this and think that a bulb has burned out which in turn causes the rapid blinking. I have included a diagram showing...

• Troubleshooting Flatbed LED Lights Hyperflashing with Load Resistors Installed
  Hey Alex, thanks for reaching out! It could be that your load resistors aren't working properly, but I'm just wanting to check and see if you've installed a load resistor on each light, or just certain ones. It would also be helpful to know if you're referring to a flatbed trailer or a flatbed on your truck. I really like the Load Resistor Kit for LED Turn Signals # DI34ZR and I've used it before when I needed to get an LED light on a hitch cover to work properly.

• Troubleshooting Dim Turn Signals After Installing Load Resistors
  It sounds like the ground connection may need to be improved. You want to make sure you have a bare metal to metal ground free of corrosion or debris. Load resistors should not have caused them to dim when installed properly. I've attached a photo of the installation for the Putco load resistors # DI34ZR to assist. If you did install this way, let me know and we can continue to troubleshoot.

• Troubleshooting LED Trailer Lights on 5 x 8 Foot Tilt Trailer
  If you used the Trailer Tail Light - 6-Function - LED - Submersible - 11 Diodes - Red Lens - Passenger # STL8RB then I recommend running a jump wire from the frame ground at the light to the mounting hardware on the unit. It sounds like the ground is not making a full contact, so the 12V battery is giving enough power to overcome the ground issue. I've attached a video of this particular light and the ground wire connection to the mounting hardware. The other possible issue is that...

• Troubleshooting Right Blinker Flashing At Double Speed With 4-Way on 2016 Ford Escape
  Hi James; does your 2016 Ford Escape have LED lights? If so, this is hyperflashing and installing load resistors # DI34ZR will fix it. If not, I would say it is a ground issue. Double check the ground on # 118566 to make sure it is secure. If you didn't clean the area underneath and it has dirt or rustproofing the connection won't be good which would explain the issue.

• 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...

• What Can I Use to Power LED Trailer Lights w/Vehicle that Converted to LED Taillights?
  Hi Bob, You're correct that the Curt 2 to 3 Wire Taillight Converter part # C56196 won't work with the LED lights on your trailer. Since your taillights on your 2009 Nissan Rogue have been converted to LEDs and your trailer has LEDs there's likely not enough power draw for the vehicle to recognize that a trailer is attached. If your trailer lights don't work at all, I suggest testing for function at the vehicle's 4-flat to make sure that each wire has power. Once you've made sure all...

• Do I Need a Load Resistor When Upgrading Trailer Lights to LEDs?
  Hey Peter! If you can find an LED compatible 2057 bulb then yes you can replace it but we do not have one so sorry I can not help you there. As far as adding a resistor goes, maybe? You may not need load resistors when you switch to LED bulbs. The best thing to do is to try the lights without load resistors first and see if you have any issues. If you experience hyperflash on the turn signals or the LED lights do not have enough draw then you'll want to add one per circuit using the...

• Load Resistors for 2018 Toyota Tundra and 2010 Airstream with LED Lights to Remove Error
  The load resistors # DI34ZR put out 6 ohms resistance each and you most definitely can install them yourself. I've attached a photo of the correct installation method to assist. They will get warm to the touch but you can absolutely install them on the inside of your RV where the wires come in from the tow vehicle. I wouldn't put anything right up against the fins as that would further reduce cooling and increase heat, but you won't have any issue in the location stated. The 7-Way...
