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 Jessie Zdunich

This is more difficult to install than regular bulbs as the blue o-ring head moves in the picture to be compatible with multiple models. And it comes off. The black mount is only held in place by 2 tiny white O-rings on the flashlight's red body. This causes all the light to slip out right after spinning. Nothing else holds it in the up and down position when prompted to install it, nor when assembling the jig. I just hope they don't fall out as I drive down the street. Everyone. I might come back if I have problems. ***EDIT*** So support contacted me and I explained the issues I was having (didn't stay although they haven't failed and are still flickering). They sent me to a site to buy a $12.99 decoder/resistor and that fixed the flickering problem. I didn't like that I had to buy something else to make it work, but they were kind enough to refund me the difference in the purchase, so I changed my review.
