Review on Ultra-Bright 2022 AUTOONE H4 9003 HB2 LED Headlight Bulbs - Hi/Lo Beam, Easy Plug and Play for Car & Motorcycle High/Low Headlights - IP67 Waterproof 6000K White - Pack of 2 by Eric Wright

I always buy H11 as my family and own many cars with these bulbs. This is my first headlight with CSP chip. I have to say I'm very impressed with them. I've tried both low beam and fog lights. I get a lot more light compared to the standard, especially the roadside lights. The build quality is good and it seems to dissipate heat adequately without a fan on the back. Personally, I'm not a fan of putting a fan behind LED lights, as dust and moisture can wear them out prematurely. The pun is not intended. Definitely recommended and I've had good customer service with Autoone in the past.
