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 Joshua Garris

Replaces the stock 9006 HB4 halogen bulbs with these Firehawk LED bulbs. Installation was very easy and took about 5 minutes. They are very bright, much brighter than halogen lamps. I've considered going with another brand that has a total light output of 20,000 lumens (10,000 each), but some users have found that they glow in oncoming traffic because those bulbs were too bright. I like 15,000 lumens. Bright enough and at the same time not too bright to disturb others. The seller gives a 2 year guarantee, I hope it lasts a long time.
