Review on Upgraded Firehawk 2021 9006/HB4 LED Bulbs - 15000LM Japanese CSP, Enhanced Brightness by 🔦 400%, Improved Night Visibility by 200%, 6000K Cool White, Halogen Replacement Conversion Kit (Pack of 2) by Josh Whitehead

I tried another brand but it wasn't brighter than my halogen bulbs so it didn't last long. These little ones shine a little, I would say at least 50% brighter if not more than my native halogens in my KIA. The only problem was that I had ordered the headlights and the fog lights at the same time and when they arrived it took me 10-15 minutes to play around with the first set only to realize they had put them in the wrong boxes. Maybe they were a return and a previous buyer changed them, I don't know. But once I figured it out, I spent less time installing them than figuring out they came in the wrong boxes.
