Best Accessory Power Relays of 2026

"I swapped out a failing relay in my car's lighting system with these and was impressed by the perfect fit and quick installation. They've handled high loads without issues, even after long use. Great value and solidly built for the price."

"After putting this relay in our Jeep, my husband was happy to report that the license plate light finally works. It definitely does the job!"

"I used this relay to replace the starter relay on my 500cc UTV. After the switch, the UTV started right up—no problems at all. Also, the shipping was impressively fast."

"I put these on my Ford F250 and they've been working great for over three weeks. I even tested all of them and they passed. The installation was straightforward—I removed a metal piece easily, which could be useful for adding extra parts later. Overall, I'm very satisfied with the performance."

"I picked these up for my Kawasaki KLX230 LED turn signal upgrade. At first, I noticed they were super lightweight, which made me doubt the quality, but they didn't feel cheap either. After installing, I had some issues with the blink rate and the signals acting up. However, after adjusting the blink rate, everything started working properly. So far, they get the job done, but I'll have to see how they hold up over time, especially since my bike's wiring is a bit more complicated."

"I purchased the 4-pack and found it to be a great value compared to local stores. Three out of four flashers worked perfectly, but one didn't function out of the box. I reached out to support, but haven't heard back yet. Still, the ones that work are good quality for the price."

"I looked over one relay last night and was impressed by the solid build and thoughtful design—from the sealed plugs and color-coded wires to the clear schematic for wiring options. The mounting lug feels sturdy, and the pack seems like a great value for the price. If the relays hold up, I'd happily recommend them."

"All of the relays worked flawlessly in our projects. They’re well built and have performed in every setup we tried so far. Out of the five, we used four, and I can confidently say they're reliable and of good quality. Would definitely buy again."

"The relays arrived quickly and after using them for a while, I've had zero failures. They’ve been dependable and effective in my setup."

"I've used this relay on my boat brakes, and the installation was straightforward. So far, it has performed flawlessly under load."

"After burning out other relays with my Hellcat pumps, I decided to try this one. The build quality is impressive, and the included copper eyelets make for upgraded wiring connections. I'm optimistic about its durability."

"This 200Amp relay was the perfect solution for replacing my vehicle's manual cut-off switch. It's much smaller than manual switches and easy to control from inside the cab. My only minor gripe is that it didn't come with the right size ring terminals, but picking up the correct ones locally was easy. Overall, I'm very satisfied."

"I used this relay to hook up my air horn to my standard horn, and now every gentle honk is replaced by an earth-shattering blast. Installation was a breeze thanks to the clear instructions and sturdy 12-gauge leads. It's built tough and waterproof, easily surviving heavy rain. It’s a bit bigger than expected, but that’s no issue—it’s the core of my custom setup. I highly recommend it for anyone who wants power and reliability."

"As an electronics expert with 45 years of experience, I can confidently say this relay is well-made with quality brass terminals and solid weatherproofing. I used it to fix a voltage drop issue on my old tractor, allowing the starter to get full power again without replacing the entire harness. The materials, like the wire insulation and the relay housing, are top-notch, and the design makes installation straightforward. I’m impressed with the value and performance so far."

"I installed this relay for my reverse camera issue, which was due to inconsistent power supply. After wiring it up, the camera now works perfectly every time I shift into reverse. The straightforward fix at a great price made it easy to recommend for anyone facing similar issues with their vehicle electronics."

"I used this high current 12V relay to upgrade my Malibu Response Skiboat with a second battery. The installation was straightforward with some additional wiring and switches. Now, I have two operating modes for my batteries, improved starting current for my V8 engine, and double the amp hours for accessories. The isolator makes sure my backup battery doesn't drain the primary, and I always have power when I need it."

"After struggling with battery drain in my 2004 Yukon due to electronic draws, I had this relay isolator professionally installed with a second battery. My vehicle now starts strong every time, and I don't worry about getting stuck. The relay keeps the second battery isolated when parked and uses both for starting. Installation is easy if you're familiar with auto electronics. I definitely recommend it for similar needs."

"I replaced my old solenoid with this relay because I was experiencing a voltage drop and my lithium battery wouldn't fully charge. This relay was half the cost, a direct replacement, and now there's no voltage drop at all. So far, it's working perfectly in my dual battery setup."

"I bought these to replace the relay in my ATV's Nilight light kit. It was a perfect fit and worked exactly as needed. Just make sure you mount it upside down to avoid any water damage to the connections!"

"I used this relay to wire up additional lights on my ATV. It allowed me to tap into the headlight circuit easily, so my LED lights come on with the headlights. Everything functions perfectly."

"These relays outlasted the original ones in my train horn setup and cost a fraction of the price compared to OEM replacements. Definitely a solid value."

"I've installed these in my headlights and other areas and found them very easy to use and reliable even in rainy conditions. For what they cost, I'm extremely satisfied and plan to update my review if anything changes."

"In my automotive shop, these relays have become a go-to solution. I appreciate not having to pay high prices for replacements—these are both affordable and function just like OEM parts. The removable mounting tab adds great flexibility, whether I need to fix them in place or fit them into a fuse box."

"While searching for decent relay kits, I chose these because of the longer wire length (about 9 inches) and the legit heavy-gauge wires for the load circuits. Although the ends aren’t pre-stripped, that’s a minor issue compared to their solid build."

"I'm rough on my SXS and take it through deep water regularly, fully submerging it. These relays perform flawlessly for the price, lasting an entire season even after repeated submersion."

"Since I tend to blow through relays, I keep coming back to these. They’re much cheaper than what Polaris charges, yet they have the same specs and markings as the originals."
