Optronics Load Resistor Dimensions

Hyperflashing (or rapid blinking) of turn signals can occur when you switch from incandescent lights to LED lights. LEDs draw less power than incandescent bulbs, which often causes your vehicle to think that the bulb is burned out or about to burn out. And this is what leads to hyperflashing. This load resistor prevents the LED turn signal light on your truck or trailer from hyperflashing by mimicking the power draw of an incandescent light.

Spoke with Andy at etrailer. Explained to him my issue with the Komo storage box's one taillight remaining on when my motor home (2014 Sprinter 3500) not powered. As in key in hand. He suggested the Optronics Load Resistor. The resistor arrived within 2 days and within 2 hours the problem was solved. Excellent customer support and product.

Wotks perfectly. Simply amazing. Easy to install. Just plug and play. Doen't show any faults of light control module /LCM/ of my truck 2006 VOLVO VNL430. No rapidly flashers. Exactly how seller explain. Drivers, safe you a lot of money and time at any Volvo dealers to reprogran LCM to works with LED stop, tail and turn lights. If i know that this resistor kit can works with my reverse back white light too /the principle i think is the same/ i can by one more resistor kit for reverse light to complete the back looking style of my truck. One more time big thank you. Strongly recommended to everyone. Fast shipping and delievery too.

Product is as advertised. Good quality. Plug and play. Unfortunately, it did not work to fix the hyper flash and bulb out chime on my 2007 ram 2500. Installed flatbed with LED lights. Bought these to plug into the LED lights. Six total flashing/brake lights on flat bed. Six plug in resistors. Lights work fine. Hype flash and bulb out chime remain. Beware.

David, This does sound uncommon with these load resistors. After a few minutes of use, all 6 load resistors should be hot to the touch, can you please verify this? If one of them is not hot to the touch, that may be defective and could need to be replaced.

by:
Seems like good quality and easy to install unfortunately it did not fix my hyper flash turn signal issues.
by:
Worked out perfectly! My grandfather had a World War II "Ben Hur" trailer he restored, and he had added led lights. He passed it down to me and my mother.

My old pickup truck did not like working with them, and caused problems even with the transmission shifting. After incorporating these resistors, every time I've had it hooked up and towed it around, everything has worked beautifully, and no more electrical issues!
by:
Item was as described and arrived when it was scheduled to. LED trailer lights worked correctly after installing resistor pack. Having plugs on both ends of the pack made it simple too install.
by:
Worked great. I bought these for my 2015 Silverado 2500 that we put a Bradford built flatbed on that had LEDs causing the blinker to hyperblink. I put one resistor on each side and it fixed it. I did not need 3 per side even though there is 3 lights on each side of the trailer that blink.

They worked great slower the flashers down and took a couple minutes to install. Awesome product

Do you have a question about this Accessories and Part?
  • Troubleshooting LED Lights Not Working On Trailer
    The first thing I recommend doing is to check that the ground wire for the lights is securely attached to a clean metal surface on the trailer frame. A loose ground wire will keep the lights from working. If the ground attached to the trailer does not give you an adequate ground, you can run the wire up to the ground circuit on the trailer connector. Next, you want to make sure the wiring on the trailer is wired correctly and wired by function, not just by color. I recommend using a...

  • Alarm On My 2022 Ford F-150 Goes Off When I Disconnect Trailer While Truck Is Off - Is This Normal?
    Hey Ron, thanks for reaching out. I have heard of this issue with some newer Ford trucks. The low voltage flash issue you are describing is normal. The truck will send a signal to the trailer to check for connection. The low voltage flash will only happen with LED lights and there is really no way around it. The amount of power sent is very small so you really do not need to worry about the battery draining. It is best to disconnect the trailer though, but that leaves us with the issue...

  • Recommended Load Resistor Kit for LED Turn Signals on a New Flat Bed
    Hey John! You'll need to install one of the Load Resistor Kit for LED Turn Signals item # DI34ZR on each of your tail lights. This is a 2-pack. I do not have, or am aware of, a load resistor set up that would handle all of the LED light's with one part. What kind of flatbed did you install?

  • Lights Flashing When Towing a Trailer with LED Lights
    Hey, Jeff. Thanks for writing in! Some vehicles can have light issues when you're towing a trailer with LED lights. LED's draw less power than an incandescent light thus causing the flashing. There is a fix for it! A load resister will make it seem like you have incandescent lights on your trailer instead of the LEDs. If your trailer lights use a PL-3 type connector you can use Optronics part # ALEDRST2B. If not, we do carry a hardwire in option, part # DI34ZR. I attached a diagram of...

  • How to Correct Flashing LED Trailer Lights Using Load Resistors
    High-efficiency LED type trailer lighting pulls much lower current than standard incandescent lights and sometimes this can cause odd behavior from the wiring harness when it cannot recognize the connected trailer. There's a simple solution to this issue: installation of a load resistor at each affected LED light. Load resistors mimic the electrical signature of incandescent lights to let the trailer wiring work as intended. If your trailer lights use a PL-3 type connector you can use...

  • Solution for LED Boat Trailer Lights Hyperflashing With 2008 BMW X5
    You are correct that you should not submerge load resistors such as the Optronics Load Resistor for LED Lights # ALEDRST2B you mentioned but there are a couple of solutions that won't require you to switch from LED to incandescent. The first would be if your 2008 BMW X5 has a 7-way; if so you can use the 7-Way to 5-Way/4-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR or Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV...

  • Recommended Load Resistor Adapter for Hyper Flashing LED Lights on Chevy Flatbed
    The Optronics Load Resistor for LED Lights - Male PL-3 Plug and Female PL-3 Plug # ALEDRST2B will create more of a load draw on your system to stop the hyper flashing. I can't give you an exact number needed as it may only require one for each system function. I'd start with one on each side at your tail lights. This will create the needed power draw on your running lights, brake lights, and turn signals.

  • Will the Optronics Load Resister # ALEDRST2B Give Me Turn Signals with My Optronics Tail Lights?
    For your 2020 GMC Sierra 2500 HD, the Optronics Load Resister # ALEDRST2B will solve the issue. However, it is important to note that the # ALEDRST2B comes with a plug-in on the end. If you need the harness that allows you to hardwire it with your vehicle, that is the Optronics Load Resistor for LED Lights - Male PL-3 Plug and Pigtail # ALEDRST1B. In order to determine which harness you need, I went ahead and attached videos for you to check out.

  • Availability of 3-Prong Pigtail Plugs with Load Resistors
    The Optronics Round LED Trailer Stop, Turn and Tail Light # STL42RB does use a 3-prong plug for electrical connection. We offer right-angle 10-inch pigtail plug # A47PB and straight pigtail plug # A45PB. Neither of these includes a load resistor, which can be required on some wiring systems to mimic the higher electrical resistance of standard incandescent lights. Some turn signals will hyper-flash when used with LED lights because the wiring does not "see" the load from the super-high-efficiency...

  • What Resistor Should I Choose For My Incandescent Lights On My 2009 Jeep Wrangler?
    The 25 watt Buyers Products Anti-Flicker Harness for Turn Signals # 3375621012 should be more than plenty, however to really decide between this one and the 50 watt version # ALEDRST2B, you'd need to choose the one that is closest to your incandescent light. So if your light is closer to 25 watts, you'll want # 3375621012, and if it is closer to 50 watts you'll want # ALEDRST2B.

  • Recommended LED Replacement Lights for 2005 Damon Daybreak Motorhome with Load Resistors
    The Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB will work great on your motorhome. You will simply need to use the wiring pigtail # A47PB for each light. You will simply need the butt connectors # DW05744-5. On some vehicles, when switching to LED lights, there is a load resistor needed to prevent hyperflashing but this is not always needed. If you do end up needing a load resistor, I recommend LED Light Bulb Load-Resistors # DI34ZR. You can get these already...

  • Will Optronics Load Resistor for LED Lights Help Fix Problem with Tekonsha Brake Controller
    The Optronics Load Resistor for LED Lights # ALEDRST2B puts a heavier load on the trailer wiring so since your Tekonsha brake controller, like the P3 # 90195, only connects to the trailer via the brake controller output wire the LED lights won't be the cause of any problems with your brake controller. The load resistors help to keep the lights on your tow vehicle or trailer from hyperflashing since LEDs have much less draw than incandescent lights. If you experience hyperflashing then...

  • How to Fix Motorhomes Hyperflashing after Installing LED Taillights
    Your motorhome must have a bulb out sensor. Becasue LED's draw so much less power than incandescents, the bulb-out sensor thinks the bulb is out and causes the circuit to hyperflash. You'll need to install a load resistor like # ALEDRST2B on each lamp. The resistor would plug inline between your existing PL3 plug and the lamp for a plug and play installation. This assumes you're using the # STL23RB lamp you referenced. If you're using a different lamp, you'd use the # DI34ZR and wire it...
