LASFIT 3157 Switchback LED Bulb, 3057 4157 White Amber T3 Series CANBUS Anti Hyper Flash Front Turn Signal DRL Parking Light New 500% Bright, Only for Standard Socket (Pack of 2)

This LED switchback turn signal replacement works amazing in my 2008 Hyundai Tiburon. It was extremely easy to install - truly plug and play and it fit perfect. No hyper flashing or other electrical issues. They are much brighter than my halogens, so definitely safer for people to see me. Additionally, they make my clear look super slick and clean - like it's about a decade newer. I highly recommend it to anyone who has a car that fits this socket. I will buy from them again if my next car has halogen lights.

Nice & bright..easy plug-N-play on the tail light LED’s..& reverse lights while easy to install, we’re polarity sensitive..got lucky & put both in the right way the first time..currently working very well and would definitely recommend

Super bright! Works great on my 2018 Toyota Tacoma. Easy install, highly recommend these. Inexpensive upgrade for your backup lights.

My 2019 Silverado Trail Boss factory reverse lights were ok but pretty dim after 7 years. I bought these before those burnt out, and these will light up my entire 100' driveway and then some. I can see everything. My backup camera looks like daylight. I highly recommend them. The install was effortless. The rear light housing came out in a minute, and these just snap right in where the old ones were. They say you need to get the polarity right, so test them before you reinstall the housings. I got mine right the first time both times, either by luck or they don't need to be installed a certain way. I have had these a week, and I have zero problems. I only have nice things to say, and they're a great value for the price.

So I bought the LASFIT 7440 LED Anti-Hyper-Flash bulbs because I wanted to upgrade my turn signals to something brighter, faster, and sassier than the dull glow of the stock bulbs my car was clearly embarrassed to be using. And wow — when these bulbs work, they’re like tiny lighthouses screaming, “I’M TURNING LEFT, OKAY?!” But, plot twist: my car apparently thinks it's a European luxury model, despite very much being a used Honda. The first pair should have worked. According to science, logic, and the box they came in, they were correct. But my car was like, “LOL, no,” and threw a hyperflash tantrum anyway. Here’s where LASFIT earns their sainthood: They actually refunded me. No interrogations. No return shipping drama. No asking if I installed it during a full moon while chanting the wiring diagram backwards. Just—"Hey, that didn’t work? Here’s your money back. We got you." But I wasn’t giving up that easily. I tried again with a second pair, because I believe in redemption... and bright turn signals. And what do you know? They worked! My blinkers are now so bright, passing satellites probably register them as international distress signals. And the anti-hyper-flash? Smooth as butter. No more frantic blinking like my car’s trying to send Morse code for “HELP I’M DYING.” So, yeah—great bulbs, great company, and amazing support even when your car decides to act like a moody teenager. If you’re looking to upgrade your lights and test the limits of your car’s electrical system’s trust issues, this is the way to go.

Brightest of the bunch. After going through 5 sets of new reverse lights, these were a little bit more expensive than the other sets I got, but much brighter. I love the pure white of LEDs and swaping these out with the crappy stock incandescent bulbs was a big win. These make a huge improvement on the ability to see what's behind you when reversing which is a big plus. As for the Errors.... I tried 5 different sets of bulbls that are all listed as "CANBUS Error Free". I guess the '24 Tahoe is super sensitive or something... none of them were error free. For the tahoe, that means as soon as you put it in reverse, you get a warning message on the dash and your infotainment screen gets locked on the reverse camera (even after putting it in drive). Not awesome if you were in the middle of using carplay or something to navigate. The solution was adding inline a set of 50W 6Ohm resisters for another $6. https://www.amazon.com/dp/B0DK77MGW3 Installing lights and the resisters took around 5 minutes (not including the time to get whatever vehicle light fixture you have opened up to get to the bulbs. I only dropped my rating down to 4 stars becasue I had to add the resisters. (but again, every set I tried threw errors at me... stupid tahoe.)

I had seen these LEDs reviewed on YouTube and decide to purchase for my pickup. The install was very easy, and was truly a remove and re-plug the OEM bulbs with the LEDs. These light up the night compared to the OEM bulbs. I have purchased another set for a 2nd vehicle, since they work so well. I would highly recommend these and would buy them again.

These so far have been an amazingly bright light in my turn signals! I've converted everything over to LED and the turn signal bulbs were last on my list. In my Focus RS these blink perfectly with no hyper flash. I love how bright they are and how far they project the yellow light out. These definitely increase visibility and therefore make lane changes and turns safer. I don't know how long these will last, but I'm hoping they last a long time...I will update this review if something changes!

Amazing, these are exactly what I wanted, had for almost a year and still work perfect, the white is great and never have had hyperflash, takes 5 mins to take old bulbs out and put these in and make the car look way better. Great quality and look great.

Not compatible with Audi Q7 4M
