Because LED bulbs have little resistance on their own, they can create a "hyperflash" situation when used in turn signals. This fast flashing is similar to what your factory signal light does when the bulb is about to burn out. To prevent this phenomenon, install a load-resistor kit along with your new LEDs. Each load resistor will build additional resistance in the line to correct the flash timing of the bulb, resulting in a properly functioning indicator.

We are towing a new flat bed utility trailer that has LED lights, with a 2013 Ford Escape. The Escape would throw a bulb error every time we put on the turn signals. Additionally, the lights on the trailer were pulsing continuously. We installed these on the trailer and now everything works perfectly! No more bulb error messages from the Escape and the lights illuminate as they should. These resistors were super easy to install, literally took us only a few minutes. 447285

Sorry it took so long to get back to you, but I finally got to installing one of them. I got these because I had one go bad on my wifes Jeep. We put LED turn signals on and obviousley had to put resistors on. We bought the Recon lights direct from the manufacturer and they told us that they had resistors built into them. They were wrong. I bought the resistors from them and they are JUNK!!! One has already come unwired and quit working. I bought these from you and they already look better built. I installed it and it worked great! I will continue to buy Putco products and will no longer buy Recon products. I have other Recon products on other vehicles and have trouble with them also. Sorry for the rant. Thanks for the resistors and I will probably be buying some more from you pretty soon. Here is a pic of the resistor I put in this afternoon. 105401

The folks provided a quality product, metal heat sink casing around resister to disperse heat - much better than the cheap plastic units sold at local retailers for twice as much. Very easy install, only thing I changed was connectors so I could use heat shrink to protect connections from water. 264357

Still perform as well as when installed

  • 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...

  • Troubleshooting Trailer Disconnected Alarm on 2018 Toyota Tundra with 2010 Airstream Trailer
    A trailer disconnected alarm has to do with the trailer brake controller pin draw on the 5 o'clock pin position on most vehicles. If you have a trailer connected and the alarm is on, you most likely don't have enough draw on that pin for the vehicle to recognize connection. Normally this is due to corrosion at the connection, but on a new truck, that most likely isn't the issue. You may want to clean the connections with sandpaper and use dielectric grease # 11755 to confirm a clean...

  • Fix Potential Hyper Flashing On 2017 Land Rover Discovery
    I understand your concern that some newer vehicles have to recognize that a trailer is plugged into the connector in order for the towing functions to activate. When a trailer has LED lights the power draw is very low, but that's one advantage of LED lights. However since the power draw is so low the vehicle doesn't recognize the trailer and therefore doesn't turn on the towing features. Another cause could be that the 2017 Land Rover Discovery recognizes the lights being on the circuit...

  • Solution for Rapid Signal Flashing on Utility Bed with LED Lights
    It sounds like you may just need to install some load resistors on the turn signal circuits of your truck. The hyper flashing you are experiencing occurs sometimes with LED lights because they only draw a fraction of the power that a standard incandescent does. On vehicles with a bulb-out sensor, they are essentially tricked by this and think that a bulb has burned out, which in turn causes the rapid blinking. The same symptom occurs if you were to have incandescent bulbs and they were...

  • Troubleshooting Hyper Flashing When Using Turn Signals On Trailer Connected To 2010 Honda Odyssey
    Sometimes with trailers there is hyper flashing when using certain functions specifically if you have LED lights on your trailer. If you have LED lights on the trailer, I recommend installing the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 # P230004A-2 on your trailer turn signal wires. This creates more power draw similar to incandescent bulbs as LED's have less draw and that can create the issue you mentioned. If you don't have LED lights, then I recommend you put a tester...

  • How to Install Load Resistors
    I have added a diagram for you which details how to install the Putco LED Light Bulb Load-Resistors # P230004A-2. The LEDs will have one power wire and one ground wire; all you need to do is tap one end of the load resistor into the power wire and the other end will either ground to the trailer or the ground wire from the bulb.

  • Troubleshooting Brake Controller Output Pin on 2018 Toyota Tundra
    You do not want to add a load resistor like # P230004A-2 to your brake controller output wire. Adding an additional power draw on that wire will not help. The load resistors are intended for adding an additional power draw on lighting wires that use LED's because there is a significantly smaller draw from LED's that can cause errors or hyperflashing. Your trailer brake controller output will have the necessary draw on that 5 o'clock pin without any resistors. I recommend checking...

  • Troubleshooting LED Trailer Lights Flashing with 2015 Chevy Silverado
    The first thing you will want to do is make sure you have a good ground for your new lights; oftentimes a poor ground can be the cause of lights acting erratically and this is going to be the most likely cause for your LED lights behaving in the manner they are. It is possible that load resistors # P230004A-2 would fix the issue if you are certain your ground is not the problem. They will need to be installed on each circuit of the trailer wiring; the instructions included with this kit...

  • Load Resistors Needed When Installing Aftermarket LED Bulbs In GMC Sierra To Prevent Hyperflashing
    Per Putco, you would need 1 load resistor inline with the wiring harness feeding LED bulb for a turn signal. I believe your Sierra has two bulbs per side, one for the running lamp, one for the brake/turn signal. You only need to install Load Resistors on the circuits feeding the turn signals. I recommend the Putco # P230004A-2 resistors. Their finned aluminum body will be very effective at shedding excess heat. I have provided a diagram showing how the resistors should be wired.

  • 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 # P230004A-2. 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.

  • My 2017 Ford F-150 Reads "Trailer Module Fault” & “Turn Signal Faults” & Trailer Lights Don’t Work
    According to what you told me, since it's not the LED lights, you may want to re-check the ground on the vehicle side. Since you are not getting the proper signals to the trailer lights then you will want to start off by making sure your vehicle end connectors where the factory harness plugs in do not have any corrosion on them. make sure sure they are clean and the pins are not bent. Yes, this applies on new trucks. If they look good then you will want to check the wiring on your vehicle...

  • Load Resistor Recommendation for Preventing Hyperflash Range Rover Towing Trailer w LED Taillights
    Using relays to add the load needed for your LR3 to operate your LED trailer taillights properly is a bit excessive although it may work. Best option is to just add load resistors like the part # P230004A-2 to the trailer wiring so that the incandescent bulb load is on the circuit and you'll be set.

  • Added LED Headlights to 2005 Ram and Now the Headlights Flicker When Turned Off
    If you have recently added LED lights in place of incandescent head lights on your 2005 Ram, you can use the Putco LED Light Bulb Load-Resistors # P230004A-2 in order to eliminate the hyper-flashing or flickering that you're experiencing. Because LED lights have a lower amp draw, it's possible that they're still drawing a very limited amount of power with daytime running lights activated or the lights turned off.

  • Running Lights Staying on 1995 Chevy C/K Truck
    It is possible that the Putco LED Light Bulb Load-Resistors # P230004A-2 will remedy the issue of your running lights staying on with the LED center brake light on your 1995 Chevy K1500. Before putting the resistors on you should use a Multimeter such as # BTMT15 to see if you have 12 volts. If you do not have 12 volts the load resistors should be the solution you are looking for so the running lights won't constantly stay on. If there is 12 volts there then there is a different issue...

  • When Switching to LED's if I put in a LED Flasher do I Need Resistors
    When switching to LED's from incandescent bulbs the turn signals are the only concern. You solve this by in-line resistors or by doing what you have done and adding a LED compatible flasher which mimics the same thing the resistors do. With that said you will be in fine shape using LED's at this point. There is no need to add resistors in your case.

  • Is Load Resistor Required for Converting 3rd Brake Light to LED Bulb
    Load resistors can be required for LED lights when the vehicle wiring is unable to recognize the light's presence due to its very low power draw. Standard incandescent bulb lights draw more power and so they are more easily "seen" by the wiring harness. Load resistors like # P230004A-2 drain away some power and so they mimic the characteristics of incandescent lights. You can try a load resistor to see if it corrects the blown fuse for your IOD display but usually it is only blinking...

  • Troubleshooting Trailer Running Lights Remaining On When Tow Vehicle Is Off
    If you have LED lights on your trailer, the extremely small power draw may be enough to light your running lights on your trailer. I recommend putting the Putco LED Light Bulb Load-Resistors - Aluminum - Qty 2 # P230004A-2 on those wires on your trailer side. This will require a draw similar to the incandescent bulbs to light the trailer and there won't be enough of a draw for that when your vehicle is off.

  • 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 Putco LED Light...

  • Are Aluminum Load Resistors for LED Trailer Lights Submersible
    Load resistors like # P230004A-2 that are sometimes needed for LED-type trailer lighting are sealed when manufactured but they are not intended to be submersed in water. The best way to install load resistors on a trailer whose LED lights need them for proper operation with the vehicle wiring is to use a junction box like # 38656 or # 277-000141 mounted up near the trailer's tongue area. This will protect the resistors from damage that could occur if they were to be submersed while...

  • Troubleshooting LED Tail Light Bulbs Flickering when Vehicle Lights are Turned Off
    The flicker you are referring to with LED bulbs is known as hyper flashing. This occurs because the LED bulbs require so much less power than incandescent bulbs. So when your lights are on, the power to the bulbs is reduced due to the draw on the headlights and running lights, but when they are turned off the power is too great for proper function without adding load resistors.

    Your 2003 Dodge Ram should have a converter on the trailer wiring harness to combine the brake and turn signals on your truck's separate wiring to a combined 2-wire system. Since your truck thinks there is a bulb out on the trailer I'm guessing the you have LED bulbs. LEDs draw less power than incandescent bulbs so the truck may mistakenly recognize the low draw as a bad bulb. To solve this you can add load resistors # P230004A-2 to the wiring.
