These baby’s are bright!
These are great headlights. They are super bright. I had a slight issue with one of them after about a year. The company reached out and the issue was solved very swiftly. My 2012 Toyota Corolla is once again happy and can now see better than ever!😊

Customer Satisfied.
Excellent. Perfect fit for my 2023 Kia Forte GT Line. Even though the Amazon fit guide stated that is not does fit my car, so that was confusing when it obviously does. Anyways, Nice cool white color. Much happier with the brightness of the road verses the yellow bulbs. 9005 HB3 led lights. So far no flickering or error codes. I have the projector headlights which causes no shadows. Not too bad for $25. See how long they last now.

Works great in my 2011 Honda Pilot
These work great as DRL lights in my 2011 Honda Pilot - no codes and no errors. I’ve always used cheaper 5000K LED bulbs with external canbus adapters, but like clockwork, I'd get a “DRL bulb out” warning every 5–6 months. Sometimes I could wiggle the canbus unit and the light would come back on, but the only fix was to either replace the canbus adapter or the bulb or both. I’ve tried other integrated canbus LED bulbs in the past, but the bases were always too big to fit behind the headlight housing. These have a more compact base, similar in size to a factory halogen bulb, so they fit perfectly. So far, I don’t have anything negative to say (I’ll see how they hold up over the next 3–6 months), but two things stood out right away: 1) They are extremely bright for DRL lights, which doesn’t bother me, since DRLs are meant to help others see you and don’t shine directly at you. And 2) They have a noticeably cooler, bluish color compared to the 5000K bulbs I was using. That said, the color difference is only noticeable when comparing the bulbs side-by-side. Once I put in both of these LED bulbs, the light output is a clean, bright white light from a distance with no blue color.

They're bright.
The bulbs are bright. The only issue I had was the fitment of one isn't quite right, but it still goes in. I will just have to modify it a bit. Overall, seems to be a good bulb.
