Best Car Alternator Resistors of 2026

"I was having issues with my Dodge’s turn signals blinking too fast after switching to LEDs. After I installed these resistors, the signal flash rate returned to normal and the lights are now brighter and stable. The resistors feel sturdy, fit nicely, and I haven’t noticed any overheating. Installation was straightforward even though I’m not a pro. For such a small investment, this solved a significant annoyance—I’d definitely get these again."

"Shipping was incredibly fast and the price was one of the lowest I found. After installing LED bulbs on my 2007 Jeep Grand Cherokee, I experienced hyperflashing and no brake lights. These resistors fixed all those issues—just make sure to mount them on metal since they get hot. Now, my turn signals and brake lights work perfectly and are super bright, even with tinted lenses."

"The installation was simple when upgrading to LED turn signals in my Toyota Matrix. These resistors completely eliminated the hyperflash and worked exactly as described. I’m very satisfied with the results and would recommend them to anyone making the same upgrade."

"After upgrading my truck to LED headlights and taillights, I struggled with hyper flashing issues. Installing these resistors with some basic T-taps solved the problem instantly—they've run flawlessly for over 8 months with no flicker or overheating. The metal housing feels sturdy and helps with heat dissipation. They're an easy, worry-free fix for anyone switching to LEDs."

"When I swapped to LED turn signal bulbs in my car, these resistors eliminated the rapid blinking immediately. The build quality is excellent, and the included connectors made setup simple. They do get hot, so I mounted them on metal away from plastic, but overall, they're a reliable and budget-friendly solution for LED upgrades."

"On my 2007 Dodge Caliber, even fancy LED bulbs with canbus compatibility didn't work, but these resistors finally solved my LED error problems. I avoided the provided wire taps and went with solder and heat shrink for durability. They do get hot, so I secured them to the frame for safety. Now, my LEDs work perfectly without flashing or shutting off."

"I needed a way to control my factory Gen 3 alternator for an LS swap, and this pigtail was exactly right. The included resistor and simple wiring to a 12V ignition source made the install straightforward."

"My LS3-swapped ‘78 Firebird needed a reliable alternator charging solution, and this product did the trick. The wire was long enough to reach my switched power source, and now the alternator charges flawlessly."

"Since my Holley Terminator X Max lacked alternator control, I picked up this adapter. Plugged it in, hooked up switched 12V, and my alternator charged immediately—couldn’t be easier."

"I used these on my old Ford with LED taillights and it completely solved my cruise control and hyperflash problems. I’ve even put them on newer trucks with great results. Definitely would purchase again!"

"These went in super fast—just a couple seconds per side—and instantly stopped my fast blinking blinkers. Seriously, thank you!"

"I installed a flatbed with two LED tail lights and was hoping these would fix the rapid flashing problem. They didn’t work for me at first, but adding an extra resistor fixed it. So, sometimes your vehicle might need more than one."

"I used these resistors to successfully bypass the Security Passlock on my 2002 Chevy Camaro. It worked perfectly and solved my issue without any hassle."

"After losing the keys to my 91 Camaro, I managed to bypass the VATS system with some basic wiring and this resistor kit. No problems at all—extremely satisfied with the results."

"The kit contained all the resistor values needed to program the ignition on my 1998 Buick. Everything was included, and it made the bypass process straightforward."

"I needed to replace the side marker turn signal harness on my 2015 Mini Cooper after switching to aftermarket LEDs, and this product did the trick. The new connection works perfectly with the new harness, and I'm completely satisfied with the results."

"After upgrading to LED reverse bulbs in my 2018 Buick Regal Tourx, the reverse lights stayed on constantly due to low load detection. I used these 10 ohm, 25W resistors in parallel, and now the LEDs function as intended—no issues, good value. I soldered and used heat shrink for reliability instead of the included connectors."

"I installed these on my 1998 Honda Accord with LED brake lights since the dash showed a 'Brake Lamp' error due to the lower wattage. After some effort fitting them securely, they've been working well for two months—no more warning lights and the brake lights are as bright as ever."

"I used this product on my 86 S10 with 1157 bulbs and it completely solved my bulb-out issue and fixed the fast flashing. Worked exactly as needed."

"These load balancers are a simple and affordable fix for annoying LED flashing when upgrading older vehicles. The pre-stripped wires made installation a breeze, and the quality feels solid. I just connected them inline, and the problem was gone instantly."

"They do get pretty warm, so I'll be sure to mount them on metal as suggested. They pulled a bit more power than I expected, but overall, they measured correctly and functioned well."

"I absolutely love the high quality materials used in this product. It feels premium in my hands."

"The customer service was outstanding; they helped me with all my questions promptly."

"I've been using it for months, and it's still as durable as the day I got it. Stylish design too!"

"I was really impressed by the solid build quality of these resistors—they looked well put together and snapped on quickly. The only tricky part for me was finding the right blinker wires on my Dodge, but once I did, these fixed my hyper flash problem right away. They've been working perfectly and the price was unbeatable. I'm a happy camper and would definitely recommend them."

"I picked these up to fix the hyper blink issue on my 2007 Jeep Wrangler after switching to LED taillights. There were no instructions included, so I had to look up how to install them, but once I figured out the right wires to connect, the resistors solved my problem immediately. Just a heads up—these get pretty hot, so I mounted them on an aluminum bracket and kept them away from anything that could melt."

"These resistors worked perfectly on my 2011 Ford F-150 and got rid of the hyper flash. The resistors themselves are top notch, but I did have to swap out the included Scotch Locks for sturdier connectors to get a proper splice. Overall, I'm very satisfied with how everything turned out."

"I found these resistors super easy to install when upgrading my car’s flashers to LED bulbs. They completely eliminated hyperflash and warning lights, and the build quality seemed reliable."

"For the price, these are a great buy. Just make sure to mount them on metal surfaces since they heat up enough to melt plastic."

"These did the job of slowing down my car's fast blinkers after switching to LEDs. They work well, but I did notice they get extremely hot, so I took extra care to attach them to metal for safety."
