AUXITO CANBUS 7440 7443 LED Bulbs Amber with Built-in Resistor Anti Hyper Flash 7440NA 7441 7444 7444NA W21W WY21W Error Free LED Front Rear Turn Signal Lights, Pack of 2

Love it , very bright! Looks good. Installed it yesterday, still need to try it on for the rest of the time.

Finally! An LED that works, without extra resistors and without causing and error code and hyper flash! I've gone through a few different bulbs and failed with them all. These Auxito bulbs hit the mark! Worked immediately, no codes! No hyper flash! One minor criticism... The bulb base is not a great fit in my W21W light socket. I really had to manipulate and push very hard to get them in. I'm actually probably going to take them back out to see what adjustments I can make to help them go in better. I feel like they may be at a point that they may pop out with a solid bump. My ride is a 2020 Chevy Suburban (Premier). So they should work for 2015 to 2020 Suburbans!They turn on and off crisp, unlike the factory halogen. Red bulbs in red rail light lenses do work the best! I had my suspicions but the internet was right again!The picture does no justice. The left ones are the Auxito. The LED (Auxito as well) reverse light bulb steals some of the show. Ignore the grocery bins and installation tools :).

These do actually work on 2010’s & up vehicles with CANBUS. Most similar bulbs don’t have enough built in resistance and the “computer” thinks a bulb is blown. Good bulbs. Very bright upgrades.

Replaced the Lasfit 7443 bulbs with built in resistors after the turn signals both failed after only 21 months of use. Bought the Auxito 2025 version 7443 bulbs with built in resistors, canbus technology, and cooling fans as replacements for the faulty Lasfits. These bulbs are $22.00 cheaper than the Lasfits and are much brighter. Very happy with these bulbs and time will only tell about the reliability.

The fitment guide says that this product would not fit my vehicle, but it ended up working anyway!I tried like 3 other bulbs/brands and this is the only product that worked, so I’m happy for that. All others claimed CANBUS error free, but this is the only one that was successful. I feel like they're overpriced - ($30 something for a brake light pair). They are definitely brighter than halogen.

Bought 2 pairs to replace my current Led bulbs that were causing Hyperflash due to missing resistor. Took the plunge and bought these to try. Installation took no more than 5 minutes per pair. Hyperflash no longer an issue. Highly recommended for any compatible car. More than 5 stars deserved!
