Auxbeam B21 Series 3157 LED Bulbs Amber Yellow Built in Resistor Error Free

Very bright. Works great. No hyper flashing on my 2006 Honda ridgeline. Highly recommended. I will buy again.

I recently upgraded the OEM incandescent bulbs in my 1999 Silverado 1500 Z-71 to these LED turn signal bulbs, and the results have been fantastic. The LEDs fit perfectly into the front turn signal sockets and work flawlessly—installation was a breeze. One concern I had when switching to LEDs was the potential for hyper-flash. Thankfully, the built-in resistor on these bulbs effectively prevented any hyper-flashing, which was a huge relief. The lights blink at the correct speed, just like the OEM bulbs. For the rear turn signals, I opted for a different brand of LEDs, the iFunyLED 4PCS 3157 LED Bulbs. These are also available on Amazon, and I chose the red lights. I’m pleased to report that I didn’t experience any hyper-flash issues with them either. I tested the functionality with the headlights on, when the brake pedal was depressed, and even with the hazard lights flashing. Everything worked perfectly—no issues at all. I also used the red iFunyLED LEDs as replacements for the brake lights, and they’re performing great. This combination of front and rear LEDs is completely compatible and works seamlessly across all signals and lighting functions. Overall, I highly recommend these LED bulbs for anyone looking to upgrade their 1999 Silverado 1500 turn signals. They’re bright, energy-efficient, easy to install, and, most importantly, they eliminate the dreaded hyper-flash. A solid upgrade that I’m very pleased with!

While I can't yet comment on reliability or longevity, these white 3157 bulbs so far seem to be excellent -- bright, easy plug-and-play installation, and no hyperflash in the taillights of my '08 Saturn Sky. There is also no annoying fan hum like I was getting with another brand.

Exceptional value, installation was simple, Bright AF even during the day, fit housing perfectly, & there’s NO Flickering/ Hyper flash.

used for back up lights in my 1988 Chevrolet K3500, super bright, I can actually see to back up at night

Dear [Company Name / Customer Service], I’m writing to express my disappointment with the product I purchased from you. After only a couple of months of use, the bulbs stopped working properly and are no longer functioning as they should. I’ve decided to send the faulty bulbs back to you so that you can inspect them and determine why they failed so quickly. I expected better durability and quality, and unfortunately, this experience has been quite frustrating. While I was tempted to leave a negative review, I’ve chosen instead to give you the opportunity to address the issue first. However, if this matter isn’t resolved, I will have no choice but to share my experience publicly, including a video showing the product’s poor performance. I hope you take this feedback seriously and provide a suitable resolution.

Overkill but amazing lights

Got these to replace my burnt out front blinkers, I love how they’re dimmer when in DRL mode but get brighter when signaling. Didn’t think that function would work since I have an older car(‘05 CTS). The best part is that they don’t hyper flash, no messing around with resistors. I’m definitely buying another set when it’s time to replace the rear lights.

Se instalaron en sentra 2021 sense, plug and play, los cuartos dan una ligera luz más intensa vs los focos de filamento por que solo enciende una seccion de todos los LED, el cambio más notorio son con las intermitentes o las direccionales encienden todos los LED restante y genera un destello muy bueno, la instalación es rápida y sencilla, espero que duren mucho tiempo y por el momento quedo satisfecho, muy recomendable, actualizare en caso de que fallen
