Auxbeam B21 Series 3157 LED Bulbs Amber Yellow Built in Resistor CANBUS Error Free Anti Hyper Flash 3457 4157 Bulb 600% Super Bright Turn Signal Light, Need Resistors for Some Trucks

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!

These work reasonably well, no hyperflash on my 2012 Honda. They are well built and seem pretty sturdy, fans are dead-silent. My only issue is that they are not as bright as a previous set of 1157's I was using. UPDATE: After being able to drive a bit more at night, I find that the marker-lite mode if these is actually just a bit more subtle than the previous 1157's I had. Its still quite visible and clear, far beyond any halogen bulb. The turn-signal mode is very bright, on-par with the previous ones I had. Giving 5 stars now, definitely worth it.

Wow they are extremely bright. I installed it on my Lexus 2013 GS 350. Works great. Except that they are a little bit longer, slight challenge on installing but managed to make it work. Am so happy. Highly recommended. Another great product from Auxbeam. I bought also the DS4 led upgrade for HID . So satisfied.

These Auxbeam 3157 amber LED bulbs are excellent and work even better than expected. They are extremely bright, light up instantly, and the amber color is easy to see from a distance which is exactly what you want for turn signals. Installation was simple plug and play, and I had no hyper flash or warning issues. Great upgrade over stock bulbs and I would definitely buy them again.

I wish I knew how to return this product it was expensive and yet still didn’t work properly. Still hyper flashes. I wouldn’t recommend this product.

Top notch product. Replaced my turn signal bulbs with these. Super bright and NO hyperflash!

This is by far one of the best LED products out there. Now if you are wondering then why the 4 not 5 stars. That is because it didn’t last 1 year. This is my second pair because the first ones turn signal led went out. Halogen bulbs would have lasted at least 2 years minimum and would have cost less then 1/3rd the price. LED bulbs are supposed to last about 50k hours of life which would have been the remaining life of the vehicle. Then again being made in China has its advantages as well as disadvantages. So 4 star is a reasonable rating. It is a really great product though and I do recommend it.

The part was exactly what I ordered. Unfortunately, I ordered the wrong bulb. I needed a switchback bulb instead of just the Amber bulb. I did not know the bike had DTRL. So, I had to return. But, the lights worked correctly and were quite bright.
