Best Car Flashers of 2026

"I upgraded the headlights on my 2007 Silverado to LEDs and started having hyper flash problems. This relay completely fixed the issue without needing to add any resistors. Installation was quick and hassle-free—I'm really happy with how well it worked."

"After switching all my lights to LEDs on my 2004 Silverado 3500 Dually, I experienced rapid flashing. This flasher was easy to install—just pull the bezel and access door, swap it in, and it’s good to go. No more hyperflashing for months now!"

"This flasher kept my LED turn signals blinking at the right speed on my 2003 Sierra. However, when I needed to tow, I realized it didn’t allow my trailer brake lights to work, so I had to swap back to the OEM part for towing."

"For my 1996 F150, this flasher was a perfect fit and worked flawlessly. It's truly plug and play, and I had no issues whatsoever with installation or function."

"I tried this flasher on my vintage vehicle with paired 1157 bulbs at each corner. While it does the job, the blinking speed was a bit too fast—not as rapid as if a bulb was out, but still noticeably quick. After some research, I learned that the 550 model is best for 3-bulb setups, while the 224 is intended for 2 bulbs. It works, but the bulb compatibility could be clearer."

"I've always relied on this flasher, so I ordered it again. What arrived was a generic, cheaper version. It still functions, but I was expecting to get exactly what I ordered, not a substitute."

"Installing this relay on my 1997 F150 was a breeze—just 10 minutes with a couple of sockets. The LED turn signals now flash at the stock rate, and it’s so much quieter than my old, noisy unit. I hope it lasts, especially since Ford tucked it in such an awkward spot."

"After switching my 2000 Ford Ranger's taillight bulbs to LEDs, I tried this relay, but unfortunately, it made both rear signals and the cab light flash together. I ended up replacing it with a different brand, and that one worked perfectly."

"I put LED flashers on my 1994 Mustang GT and dealt with fast blinking and non-working hazards until I installed this relay. Now everything functions as it should, although the clicking sound is a little unusual—but that’s a minor issue compared to the improvement."

"After switching to LEDs on my '54 Chevrolet, the original flasher wouldn't work at all. Swapping to this unit solved the issue instantly—now my turn signals function as they should. I'm planning to keep a spare on hand just in case."

"The auto parts store tried to sell me a pricey $200 turn signal handle, but this flasher fixed my problem at a fraction of the cost. Installation was quick, and everything works perfectly now."

"For my LED conversion, this flasher was a perfect fit. It's a bit taller than the original, but everything flashes as it should. Very happy with the results."

"I found the installation process super straightforward, and it worked perfectly as a replacement for my 1982 Honda GL1100’s OEM relay. This solution made my switch to LEDs pretty seamless."

"After converting my 97 F250 to LED lights and signals, this relay was the only one that actually worked for me. My only gripe is that it's about half an inch taller than the original, so the fuse cover no longer fits, but otherwise, it's a solid fix for the fast-flash problem."

"I thought I'd solved my LED bulb issues with this flasher, but unfortunately, it didn't resolve the weird electrical glitches I was having. Once I put the old bulbs back in, everything worked again, so this product just wasn't compatible with my setup."

"After adding LED turn signals to my Honda Ruckus, the original flasher stopped working. I swapped in this relay and the installation was a breeze—now everything works perfectly. Highly recommend for solving LED issues!"

"I picked this up for my 2020 Kawasaki Z900RS Cafe after switching to LED signals. No more hyper flash, and I haven’t noticed any problems like others have reported. So far, it’s working flawlessly."

"I used this relay on my Honda CB650 custom. It did the job, but I needed to modify some wiring and connectors since it wasn’t a direct replacement. After the tweaks, it runs fine and my signals work great."

"I was impressed with how quick and simple these were to set up and the super bright flicker at startup. I just wish they included wire connectors for those who don’t already have them."

"These modules are perfect for boosting my motorcycle’s brake light visibility. After installing the first one, I noticed a clear difference and decided to add the second module to my other bike. The price was unbeatable too."

"Unfortunately, my set didn’t work at all—no matter how I wired them, there was zero response. I’m only giving a star because a rating is required."

"I found the installation to be super easy—just had to connect the ground wire to the chassis. It completely solved the turn signal issues on all my cars after switching to LED lights."

"After converting my 1970 Chevelle and 1972 C-10 to all LED bulbs, I learned that only this grounded flasher worked correctly. However, I did notice that the ground wire attachment could be better—it’s not the most secure, but it still gets the job done."

"Once I realized I needed to reverse the polarity by switching the leads, these flashers worked well for my classic Mustang. At this low price, it’s still a good deal, even if it is a universal item likely made for European cars."

"I switched to this flasher for my motorcycle and classic car after struggling with another brand. It fit perfectly, works silently, and keeps the blinkers flashing at a steady pace. I'm pleased it’s compatible with older bikes and cars, and the sealed design gives me confidence in its durability."

"After swapping out all the incandescent bulbs in my vintage motorhome for LEDs, I had to deal with an annoying hyper flash. This flasher solved the problem instantly—no more fast blinking! It fit right into the original socket, and the quality feels even better than the stock part."

"I installed this on my 1972 Yamaha R5 after updating to LED bulbs. The flasher wired up easily and operates quietly, which I actually prefer. So far, it’s working great with my setup."

"I replaced the relays on my Ford F250 with these and have been using them for over three weeks now. All tested good and installation was straightforward. I appreciate the option to remove the metal piece if needed, and it gives me flexibility for extra parts. Thumbs up for reliability and design!"

"When I upgraded my Kawasaki KLX230 with LED turn signals, I installed these relays. At first, there were issues with the blink rate and function, likely due to my bike’s extra light features, but after some adjustments, everything worked as expected. They’re super lightweight and seem well made, but time will tell for long-term use."

"I bought the 4-pack and found the price unbeatable compared to local stores. Three out of four worked perfectly, but one unit didn’t function out of the box. Overall, great value, but I wish there was a quicker response from support."
