2025 CANBUS 7440 7443 Amber Yellow LED Bulbs with Built-in Resistor Anti Hyper Flash 7440NA 7441 7444 7444NA W21W WY21W Error-Free Front Rear LED 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 LED turn signal bulbs are extremely bright. I installed them in the rear turn signals on my 2020 Ram 1500 Big Horn, and the difference compared to the factory bulbs is immediately noticeable. As you can see from my pictures, they put out a very strong, bright amber light and are easily visible even during the daytime.Brightness & Safety: These are MUCH brighter than the factory turn signals. The bright amber output makes my signals much easier for other drivers to see, especially during the day.Flickering: No flickering so far. The light output is bright and consistent when the turn signals are operating.Quality: The bulbs feel solid and well made. I also like the built-in cooling design on the back of the bulb.Ease of use: Installation was straightforward. I removed the factory bulbs, installed these LEDs, and they worked great.Appearance: The amber color is very bright, crisp, and clean. They give the rear of the truck a much more modern LED appearance.Durability: So far they’re performing perfectly, and I’ll update my review if anything changes over time.Overall, this was a massive upgrade over the stock rear turn-signal bulbs. If you want something that people can actually SEE when you hit your turn signal, these definitely deliver. 5/5 — highly recommend!

I'd like to preface this review by saying the bulbs didn't last long and while I'm not very happy about it, I still went ahead and bought another set because I just love how bright they are!So starting with the good remarks, they are extremely bright. I had bought the red 7440/7443 bulbs for the brake lights on my 2013 Subaru Outback as well as the amber/yellow colored ones for my turn signals, along with other LED bulbs from Auxito. These ones are bright enough to illuminate every reflective sign around your vehicle, and I found that they have a good light coverage (though that largely depends on the light housing design of your vehicle). The red ones are perfect for brake lights, red is the hardest color to make bright but these do the job! They are much brighter than a standard incandescent bulb which makes it easier to see during a sunny day and very noticeable in low light conditions. They are comparable in brightness to LED brake lights on modern cars. The yellow/amber versions are arguably too bright, perfectly fine for daytime use but at night, they can be blinding especially the rear turn signals. I feel bad for anybody sitting behind me at a traffic light when I'm waiting to turn. The front turn signals work nicely compared to the bright headlights they're next to and their beam pattern on my car point most of the light upwards, so they're still very noticeable but not blinding. However, my rear turn signals point the light straight back into people's eyes and with only red lights back there, it's a little too bright/harsh. I've seen other drivers literally shield their eyes and put down their sun visor at night because of my turn signals. Again, this mostly depends on how the manufacturer of your car designed the reflectors inside the light housings, so not really a fault of the bulbs. I can also say the built in resistors do work perfectly, not a factor for the brake lights in my car but the turn signals work as expected, no hyper flashing ever. German cars can be a bit picky but they should work without issue on just about everything else.Now onto the bad parts. This car was still pretty new to me when I swapped in the brake light bulbs. I started noticing a fan noise when I was stopped at lights, I thought my radiator fans were going full speed for some reason until it dawned on me that this noise started after I put these bulbs in. The cooling fans on these are loud, not obnoxious but you can certainly hear them when you turn down the radio. They are louder when they're cold and get quieter as they warm up, only takes like a minute or two of run time for the noise to die down. So I always notice them when I leave for work in the morning hitting the brakes for the first time. But after you get going, any amount of volume on the radio or road noise will usually drown out the remaining fan sound. The brake lights aren't the only ones affected by this, I hear it on the turn signals too. This is completely tolerable but I'm not sure how effective these fans are because I started having issues with my brake light bulbs just the other day. I checked my lights when I changed my oil about 1 month/1000 miles ago, everything was fine. But then the other day on my lunch break, I was reversing to park in front of a store with glass windows and saw my driver side brake light flickering. I checked the bulbs when I got back to work and found half of the LEDs on that bulb were not working. Additionally, the bulbs seemed dimmer than they should be, like they have been slowly losing their brightness since I last checked. I ended up going home and swapping my original incandescent bulbs in that I held onto since buying these. For a product that advertises a 50,000 hour lifespan, this is simply not true. Had the bulbs been running 24/7 since I bought them a little over a year and a half ago, it would only be around 15,000 hours. And obviously they were not running the whole time so my actual time with them would be significantly less. My car is a manual transmission so I'm not even on the brakes as much as I would be in an automatic transmission car. This false advertising in addition with charging 3-4x the price compared to incandescent bulbs for less than half the lifespan is why I can only do 3 stars. But like I said, I really like the brightness of these bulbs so I wanted to order another set. We'll see if I have better luck on this go around, maybe I had received a bad batch. My turn signal bulbs are still working fine but now after this, I'm not expecting them to last much longer.

Really happy to see resistors built in that are reliable. I kept having to splice in resistors that would go bad after a few months. These are a little spendy but worth it to no have to keep wiring them yourself. After 6 month they are still working great. Installed 4 of them on my 2017 Colorado

These are good lights, and the bright flash for turn signal/emergency lights is very very bright, almost blinding if you look right at it. Bright is good but if it's ever possible to take the harshness out of the direct light, that would be very nice.The built in resistor to eliminate hyper flash only seems to work correctly if all the bulbs on that circuit are this same led bulb.I discovered this after ordering them, I had ordered the wrong fit for my back lights, so installed only the front turn signal bulbs, leaving the back bulbs the original halogens, while waiting for delivery of the rear led ones. I often had intermittent hyper flash. I contacted the company, they sent me a set of resistors to correct the problem, however I received my rear led bulbs first, and after installing them, the hyper-flash issue almost completely went away. So no need to install those resistors after all.One issue however, after using the high power flash of the emergency lights, they do seem to overheat a bit, and when turning the emergency lights off, and immediately using turn signal after, it does hyper flash, I assume the resistor stops working correctly when it's too hot. If I turn the signal off and let it cool for a few seconds, the flash returns to normal.In my opinion this is a flaw and the design should be modified, and could be fixed by having the fan run off a thermometer, instead of only running when the flash turns on. Or a slightly more powerful fan.They use very little power when in parking light mode, a little more when in flash mode, but still much less than halogen which is great.I'm very happy with company's support system, and always have loved their bulbs and rated 5 stars, however this bulb gets the 3 star rating for the slight overheating issue. That should have been corrected before sales in my opinion, especially considering these bulbs are not cheap.
